I know I posted about this yesterday, but this article does a much better job than I can.

    I was watching dashcam / accident videos and I’d seen one where a car got disabled in the middle of a highway underpass, which was a blind crest. Car after car after car would enter the underpass, unknowing of the disabled car there, and make emergency maneuvers, barely missing the car every time (and some didn’t). Several vehicles crashed at full highway speed into either side of the underpass trying to avoid the disabled car.

    That doesn’t sound like safety to me.

    As for trains, remember that trains only need to keep track of one axis of motion, the forward axis, as the train is not going to be maneuvering, as that would cause it to derail if it even could. Maximum speeds are a known factor on the line, and accurate timing is important to coordinate multiple trains on a line. Cars aren’t trains, and the requirements are a lot less predictable.

    Will the software know the difference between winter weather and drunk driving?

    Will the software know the difference between a windy mountain road and drunk driving? How about drunk driving on a windy mountain winter road?

    How about fix the problem of drunk driving being so prevalent, instead of adding additional points of failure to an already overly expensive vehicle?

      Sounds to me like the real issue there was the design of the road being such that it didn’t have visibility.

      Technically that’s not true, they keep track of way more than that. But I understand what you’re getting at, and it doesn’t quite hit what I’m getting at.

      I’m saying we have a pretty good idea of what goes into a safety system on incredibly dangerous vehicles (trains), and some of it can be transferred to another set of incredibly dangerous vehicles (cars).

      If you’re swerving like you’re drunk in winter weather, are you really arguing that you should be allowed to keep driving? If you’re swerving at high speed in winter weather, you’re already doing something wrong and going to get somebody killed.
