> very least it'd be handy to have self-driving at least on, say, highways Me too, like driving home after a long day on the highway, being sleepy, in the night, while raining. Good luck with that: [1] [1] https://9gag.com/gag/azMv16z https://9gag.com/gag/azMv16z

  lol, have you seen humans try and drive in the snow? Especially any of them who have AWD/4WD and snow tires makes them invincible? If you've ever had to brake in below-freezing conditions and ABS has kicked in, you're already trusting a computer to be better than a human at that task. Now granted, ABS is a far more limited system, with way more limited inputs and outputs, so the calculation and algorithms and code involved are dramatically easier, and self driving cars have a long way to go still, imo, but trivializing it to "lol snow" disregards the interesting technical challenges involved before self driving in snow can be solved for. You seem to think you have some expertise driving in winter - what is the biggest single challenge that self-driving cars face trying to drive in the snow?

    > lol, have you seen humans try and drive ... This hints at an interesting issue. The difficult problems with self driving are not going to be the technical ones (driving in X environmental conditions) but the social ones. Self driving cars are going to need a theory of mind (be able to make good guesses about what mistakes other road users could make), and also behave in ways that don't make human road users uncomfortable. The latter is relatively easy, but the former is hard - never mind Theory of Mind, some self driving software doesn't even seem to have object permanence. 1. https://en.wikipedia.org/wiki/Theory_of_mind https://en.wikipedia.org/wiki/Theory_of_mind 2. https://www.simplypsychology.org/Object-Permanence.html https://www.simplypsychology.org/Object-Permanence.html

    If the car takes over-the-air software updates, they are advertising up front that they don't believe themselves able to debug the car before they sell it to you. Normal ECU's, ABS brakes etc. do not need OTA updates. There is no absolute certainty about anything, but such issues are rare enough to be handled with product recalls.

  Snow is opaque to light, but not radar, which means it’s actually fairly easy to work around this in car sensor suites. The same also applies to many types of foliage and grasses. The metal content of the line paint and the material of the roadway surface and guard rails are pretty easy to differentiate with other sensors.
