Last night I was watching an episode of a cop show where they were closely trailing suspects and observing them which made me think, well there's one case where a pure self-driving car would do no good.
I would imagine it would be a while before a car that can easily get you from A to B autonomously could be told "OK follow them, but not too close and not too conspicuously. Make sure you stay out of site, but not so far out of sight I can't see what they are doing, oh and every once in a while parallel them on the next street over, but make sure we keep up".
In the end there are so many more "modes" cars are used in than just A to B I would think it will be a really long time before purely autonomous would be possible.
Then, after having that thought, I saw
this article today that basically says even the ones that work, only work in good weather.
I think I'll keep my steering wheel for now thank you, maybe throwing in GMs advanced cruise control or similar for long trips.
