Quite the qualification for self-driving: "as long as there are clearly painted lane lines."
I'm very happy with any company that clearly spells out the situations where their tech works, and the situations where it doesn't yet work.
Also, I would like to see a car company that is further down the road of full autonomy clearly describing all the long tail scenarios. It's just impossible.
Sure, you can cover everything they can think of. But there are so many cases you can't predict, or which don't have an obvious solution, and it often comes down to a human judgement call that doesn't always have a programmatically-clear right answer.
Seems like a good start to me, and I'd rather they approach as cautiously as possible.
