Numerous Tesla owners have said they’ve been stuck inside their EVs after the cars suddenly lost power.
YouTuber Tom Exton claimed that his Tesla Model Y ordered him to pull over before it suddenly lost power and left him unable to exit.
Exton followed the instructions for the manual release to open the door, but he said this “somehow broke the driver’s window.”
Tesla doesn’t use steer by wire, but some other car company do. It’s actually really nice for having a high steering ratio at low speeds and a low one at high speeds to be more precise.
Plus breaks have been brake by wire for years now without mechanical connection.
Brake by wire isn’t really very common afaik. Mercedes had EBC at some point but stopped using that system. It also had the downside that the SBC unit had to be replaced every so often to guarantee a working brake system.
From the wiki:
Seems pretty common to me.

The question now is what the other quote was talking about, seems a bit unclear to me. I omitted the electronic parking brake in the quote.
EDIT: As of now I could find references to a total of 6 car models implementing brake-by-wire, two of which are already discontinued: Toyota Prius, Lexus RX 400h, Mercedes E and SL(both discontinued), Alfa Romeo Giulia and the Chevrolet C8 Corvette.
Again, considering the current amount of models on the market, that’s far from common
The Chevy Volt, for instance, has brake-by-wire, but I don’t think they advertise it as such. Most regenerative braking systems require brake by wire to function effectively, because you need to use the regen at higher speeds and physical brake at lower speeds, but only want the user to have one brake pedal.
“Brake by wire” doesn’t mean there isn’t a mechanical linkage, just that the “primary” means of transmitting brake pressure is electrical.
Between safety regulations, liability, the the potential for a PR disaster there isn’t a single road legal car for sale (yet) that doesn’t have a backup hydraulic or other mechanical system – the brakes must work if there’s a catastrophic electrical failure.
Goddamit my whole life i thought by wire meant like physical tensile wires, that the power was transmitted through tension in the wires. Never realized theyre talking about electronic systems where the information is transmitted electronically.
I can’t find which, but some vehicles seem to not have mechanical backup.

EHBs are fairly common, but they don’t preclude the use of a backup master cylinder system. A pure EHB has been a “goal” for a long time since eliminating the master cylinder and linkages would simplify design and manufacturing cost. So far nobody has been able to convince regulators or their legal team they can sell a car without one, though.
Pure electrical throttles have been the standard for a while now.
Do the brakes brake by wire, or break by wire?
They give a feedback to a sensor which communicates over electrical wires to the brakes.

Thanks, sorry fixed now
