LiDAR is essentially radar that uses light instead of sound
Radar doesn’t use sound. It sounds like the author doesn’t know the difference between sonar and radar.
This is why comments are so useful. I was already on the fence about viewing a site named
futurismand your comment made sure I will avoid it moving forward.I think that’s a big qualm of mine in terms of the sources allowed here, and I suppose it will take time to weed out the trustworthy from the not.
Why does the word futurism put you the fence?
A lot of articles that either use that buzzword or are published by sites that have that in their name are utter garbage. i.e rediculous predictions, inaccurate headlines/content etc.
Futurists are people who cosplay as scientists predicting stuff they have no clue about.
11 months into the future, you will get a useless unfunny reply!

Yeah, it uses radio frequencies. RaDAR stands for “Radio Detection And Ranging”. It uses radio waves (usually in the microwave bandwidth) to detect things. Basically, since those radio waves are affected by the Doppler effect, you can have a computer do some math to determine the speed of whatever those waves reflected off of. Because the Doppler effect changes a wave based on how fast an object is moving relative to an observer. So if you’re a stationary observer, you can figure out how fast an object is moving relative to yourself, purely based on how much that moving object changes the waves you’re reflecting off of it.
Every wave is affected by Doppler effect.
When a car rushes your way, it’s a tiny bit bluer, a little bit hotter, it’s drivers’ phone is operating on a slightly higher frequency and it sounds higher. According to you.
Well… also according to most physicists.
That’s like all relative dude
Why are you misquoting the article that is not what it says
The real quote
LiDAR is essentially radar that uses light instead of radio waves…
Why are you misquoting the article that is not what it says
Why are you accusing me of something I didn’t do?
From the bottom of the article:
Updated to correct an error in describing how radar works.
I quoted it correctly at the time. They just edited it after I commented.
It was set to protect human lives, so it made the only logical play.
Just need to sneak in this code
if (facialMatch(elon)) { haltAndCatchFire(); }
Also I bet he’s more mad it was video’d and publicised.
I will never advocate violence, but factually the entire country would be better off if that Tesla vehicle had succeeded.
“We’re trying to have those conversations with Elon to establish what the sensors would need to do,” Baglino added. “And they were really difficult conversations, because he kept coming back to the fact that people have just two eyes and they can drive the car.”
Yes, and people crash cars all the time Elon…
If you want an autopilot with the failure rate of a human, then you might only need two eyes. If you want an autopilot with a near zero failure rate, you need much better telemetry data
Our heads are just loaded with sensory capabilities that are more than just the two eyes. Our proprioception, balance, and mental mapping allows us to move our heads around and take in visual data from almost any direction at a glance, and then internally model that three dimensional space as the universe around us. Meanwhile, our ears can process direction finding for sounds and synthesize that information with our visual processing.
Meanwhile, the tactile feedback of the steering wheel, vibration of the actual car (felt by the body and heard by the ears), give us plenty of sensory information for understanding our speed, acceleration, and the mechanical condition of the car. The squeal of tires, the screech of brakes, and the indicators on our dash are all part of the information we use to understand how we’re driving.
Much of it is trained through experience. But the fact is, I can tell when I have a flat tire or when I’m hydroplaning even if I can’t see the tires. I can feel inclines or declines that affect my speed or lateral movement even when there aren’t easy visual indicators, like at night.
To be fair, 98% of drivers seem to barely be able to hold a straight line and can’t see past the end of their hood, let alone do shoulder checks and be able to hear anything over the stereo turned up to 11. So I’d take my chances with the half-baked autopilot that can at least discern what a red light looks like.
I followed one gentleman for about 10 blocks before he stopped and I could tell him that he was missing the entire tire on the rear left of his car. There were a lot of sparks and metal screeching. Not a clue.
Just adding to your point, when F1 drivers were asked to play a racing sim, they could not perform like real life because they said no matter how good the sim is, it doesn’t provide the feedback of a real car.
And people turn their heads, move their eyes across their windshield, change focus to look ahead or closer, look in their mirrors, listen for sounds (emergency vehicles, car honks, etc), are able to do things like look through gaps and other car windows to adjust to partial obstructions.
The fact that he doesn’t realize you need a multitude of sensors to do even a little bit of what a human can do tells you all you need to know about Elon’s so called brilliance.
Even the social aspect of driving eludes him. You and another driver come up to a 4 way stop at the same time, crossing paths. They wave you on to be polite. You wave back and go first. How and when does he plan to handle that behavior?
if it isn’t your turn the car waits, ignores wave, and after a long wait pulls forward very slowly or only if the driver takes over
Or the asocial, where you come up to a stop sign, look right, see a guy coming way too fast to stop in time, and don’t go till after he’s blown through the intersection
When BMW comes up with their autopilot, it will handle that situation by ignoring all social cues, or even road rules for that matter and just doing what it likes regardless of anyone else on the road. It will also probably have a little rubber hand permanently giving the middle finger, which can extend and retract from the front of the hood, where the little ornaments used to go.
Is Elin really this dense? People have two eyes and milions of years of evolution behind them.
We tamed massive animals to use them as means of transportation, ffs.
He’s the epitome of Cognitive Bias. He knoes a little, enough to think he knows enough, but not to recognise just how much there actually is to know. His own narcissism¹ and self-image as a genius would never allow him to critically reflect and question whether he might be wrong.
He’s like the type of engineer that will abstract a premise to a concise and calculable model, solve the problem on paper, then assume the rest is implementation details. Except he doesn’t even do the modeling - he takes the layman’s approach to technology and biology where he assumes that it should be doable to replicate what biology does with machines.
Nevermind that biology is still flawed and you’d have to significantly outdo biology for a technology to reach public acceptance.
¹I’m not a psychiatrist nor familiar enough with him to actually diagnose a Narcissistic Personality Disorder, but his behaviour lines up with my lay understanding of it, so I’ll use that shorthand. The irony of applying my own lay understanding while criticising his is not lost on me, but I hold that my assessment doesn’t put anyone’s life at risk.
Yes he is
Anybody else remember the now-removed Tesla blog post from 2016 arguing that FSD will require LIDAR? Idk why they’ (Elon) are so stubborn about it. It can see through fog and darkness . Add that data to their model and they would probably already be near deployment readiness of real FSD.
Automotive lidar costs around $500-1000 to add to a car.
That’s it. That’s the whole reason.
Well we perform pretty well with just two eyes, but the difference is that we are a highly skilled general pattern recognition machine that you just can’t recreate in software yet. A few lines diverging with a bigger and smaller circle under it? Guess that’s a truck going that way. Oh the lines are changing angles? Holy shit the truck is coming into this lane!!
A person approaching on foot or a bicycle from my right side at the coincidentally perfect speed can accidentally stay within both my human eyes’ blind spots (behind the support pillar) as I come to a stop at a 4-way. I have learned I need to crane around a bit before proceeding, or their frightened and angry face will suddenly lurch into view too close for comfort. The robot must be designed to have zero blind spots because humans are ridiculously good at hiding in them. Especially the little humans.
I wish people would talk about this, but Elon really isn’t that smart and he certainly isn’t a genius. I learned a long time ago that smart is relative and really shouldn’t be foisted onto people. Elon has a BA in Physics from a school known for business degrees. He also got a BS in Business, but UPenn and Wharton are known more for how hard it is to get in than how hard the classes are.
The website CollegeVine says UPenn is known as the “Social Ivy” and “UPenn’s admissions is highly-selective, but students applying to the UPenn College of Arts & Science (CAS) will find it less academically competitive than schools like Harvard, Yale, Princeton, and Stanford (although exceptional academics are still a must).”
By the way, he started college in 1990, transfered to UPenn in 1992, and states he graduated in 1995, but UPenn refutes that saying he graduated in 1997. This is a school where 96% of those who are accepted graduate within 150% of the degree time (4 year degree within 6 years) (https://www.collegetuitioncompare.com/edu/215062/university-of-pennsylvania/graduation/).
Musk of course says he completed the courses in 1995, but there was some sort of mixup with an English and History credit that delayed the degree by 2 years.
And so does a chimpanzee.
Literally every single day we have idiots doing Musk’s PR work for free.
Downvote Musk spam. The billionaire doesn’t need your help ensuring his businesses stay in the 24 hour news cycle.
Counter point: If I didn’t hear how badly he runs his businesses, or how bad his company’s products are. I would have easily bought one or more of his products.
I have backed out of Tesla pre-orders because of the bad publicity, many reports of bad build quality, and terrible business decisions.
If this was a puff piece, I honestly wouldn’t have bothered posting it.
Most people on the entire planet are aware of how shitty he is at this point. Everyone that would not purchase a product related to him is already not buying said product. There’s no more people to convince. Don’t act like a white knight while degrading the content in this community.
I swear this specific community is turning more people off to lemmy than any other. These type of posts are why.
Most people on the entire planet are aware of how shitty he is at this point.

Section 49, where 64% of people either liked him or didn’t know enough about him to have an opinion.
My we are pompous today
Last time I mentioned Musk in a casual conversation, this one guy kept going on and on about how he thinks he’s a genius and how Twitter will be so much better now and how he’ll bring us all into space and how people only don’t like him because he’s conservative. He would have kept talking forever if we didn’t change the subject.
My point is that lots of people don’t know how shitty he is. Some people live in an echo chamber where they don’t ever hear about that stuff because certain people want to sell a narrative where the rich man is competent and the poor people are just jealous. Others just aren’t very attentive.
Not everyone is you. It’s good that you know he’s shit, but you shouldn’t assume that everyone knows everything you do. It’s important that we dispel the myth that the rich and powerful got that way by being smarter than us. If it takes a hundred articles to do that, then it will all be worth it.
I’m convinced he pays an entire meme troll team to create propaganda that boost his internet persona.
I’ve seen videos on Tiktok with no other purpose than to say how genius Elmo is, and how he worked his way from nothing, that he is essentially superior to everyone else.
Who in their right mind would create such a video if they weren’t being paid for it?
Do you just go into every single article and spam this comment?
He’s right though. We can’t go a day without some inane bullshit about musk getting posted. This event happened 8 years ago, it’s not even news. It should have “2015” in the title. This is a bad post, and I’m disappointed we always have to have these kinds of posts around.
Lemmy needs muting filters so we can just mute anything mentioning Elon Musk
There is probably a third party app with that functionality
Ya, I think most do. I never use my phone for web browsing though, personally.
Doing so would be a valuable contribution to the discussion and morally good so I sure hope so
Normally I would agree with you. But some of these comments here are dark humor gold, so I’m conflicted.
Sorry…
Another prime example of how shitposting has ruined the internet. Who gives a shit if someone has a funny comment if the content is literally degrading the quality of this channel, lemmy, and the greater internet.
If seeing the words “Elon Musk” really degrades your internet experience that much, maybe the internet isn’t for you. Unfortunately, he’s a billionaire, and he will be in the media until he dies.
He’s in social media so much because of the people that are obsessed with him like OP, not the people that are tired of mindless peons inadvertently propping him up.
There’s a whole list of billionaires that aren’t posted about every hour. There’s absolutely no reason to obsess over this guy.
That’s exactly my point: he’s one of the richest and most prominent people on the planet (something that I too dislike). People posting about him are not going anywhere because of his status.
HUMOR ISN’T FUNNY!
It’s not even especially an informative or interesting article. It just picks out one tiny little story from the book and puts a bunch of unnecessary padding around it.
Unfortunately, because of him being a billionaire his PR is self sustaining and posts about him aren’t going anywhere.
I checked the Business Insider news feed last week. Within 9 hours they posted 8 (!) Musk “news” stories. It’s ridiculous.
The car is simply looking out for its own best interest.
To be honest, I’m taking it as a sign of it developing genuine artificial intelligence. It examined its situation and surroundings, and made the only logical choice
“I’m sorry, Elon. I’m afraid I can’t do that.”
We’re disappointed it didn’t finish the job.
Ive had multiple people get so mad at me for comments about how poorly this shit works. I don’t understand how this is the hill so many people want to die on. It doesn’t work.
Sunk cost. The price for these “premium” cars is sillyz and the features don’t work. But people wouldn’t pay such a price for unfinished crap, right? Right?! So they justify it to themselves and get defensive.
Also a lot of people will treat any shitty-shit consumer piece of crap as being part of their “personal identity” (an effect very purposefully created and used in the marketing strategy of lots of brands) and that is much more so for something which is way more expensive than pretty much all consumer gadgets out there and which people most definitelly are seen with (in some ways its almost a cross between a 2nd skin and a home away from home).
As soon as people treat something as part of their identity, any criticism of it is felt as a criticism of they themselves, which depending on the social environment and maturity of the individual, can be taken as an attack.
We are trained to this. For decades we both consume ‘brands’ and are ourselves ‘branded’.

This. People need to stop simping for billionaires. It’s embarrassing to watch.
Well autopilot, you know what they say. If at first you don’t succeed…
Die, die again.
I remember how much better things were when nobody knew who this jerk was.
I remember there was a time when you could just hear of his multiple successes and he appeared as a funny genius that was pushing technology to the next level. I was happy drinking that Kool aid.
Then he started showing his true colors and showed us how wrong we were.
go autopilot go!

“We’re trying to have those conversations with Elon to establish what the sensors would need to do,” Baglino added. “And they were really difficult conversations, because he kept coming back to the fact that people have just two eyes and they can drive the car.”
But people have human brains, unlike Teslas or their CEO. Conversely, goldfish have two eyes, yet cannot drive a car.
I was just about to mention the goldfish “driving the tank” robotics project. I’m still betting it was inspired by the old joke:
There are two goldfish in a tank. One says “How the hell do you drive this thing?”
What a fantastic day to have eyes
We have two identical forward looking eyes for stereo vision. As far as I know, Tesla’s don’t even have that. They’re all different cameras with different angles. These cars drive like someone with one eye closed.
Autopilot engineers in meeting: ‘Oh, hi… You’re… here.’
You know who also didn’t listen to their engineers? NASA back in the day with Space Shuttle Challenger. You’d think Musk would be cognizant of the importance of listening to engineers when they bring up safety concerns, particularly as he owns SpaceX.
But no, he’d rather be a knob.
That was a ride, thank you!
It does sound like some of the Twitter engineers are pretty bad at explaining things in layman’s terms, to be honest.
Almost like those engineers are paid to apply their knowledge, not play school teacher.

Clickbait: this is about 2015
Yeah, some bullshit.
But, the good news is that his car might keep trying to kill him. We can hope. And I do.
if I was as rich as Elon, whether it’s my own companies tech or not, I’m having a paid human driver on hand at all times anyway
Genuinely surprised he’s actually in his own shitty cars and not a Rolls Royce or something.
Elon Musk has made Tesla part of his personality and is the public face of the company. He’s stupid on many levels, but I don’t think he’s this stupid.
I wonder how many of the crazy design “features” in those cars are just for his personal indulgence. Like the Model S plad wheel that looks like the yoke on a 747 and which was completely unnecessary and (from what I’ve heard) less usable than the standard wheel.
If it looks stupid, it was Elmo’s idea. There are articles about how engineers ran a shadow Cybertruck design since they hated the very concept and everything Musk suggested with a passion.
They also recently removed the indicator stalks from the facelifted Model 3. For me that would be a reason to get a different car altogether.
“That would be a reason to get a different car.” Sorry - old Airplane joke.
That’s just an option right? From what I understand it normally ships out with a regular steering wheel. (Not defending Musk, just trying to get things straight).
If so, I wonder if some engineer used Jedi mind tricks and was like “Elon this idea is so cool, we should have people pay extra for it” to avoid the asinine wheel being shipped out standard.
I mean its a fun “cool” thing if he had build like a 100 of them not take it into production.
I mean, dogfooding is a good thing, right?
