Laws are written and designed for humans who constantly try to push it to the limit and get away with things. These cars are all over the place and I've been caught stuck on a street in Bernal Heights because it couldn't quite fit and just froze in place. I had to back out of the street because there wasn't any room for me to go around it.
Yes it may be following laws to the letter, but not only was I grumpy about having to carefully back out of a street, there wasn't any way to communicate with the car. It doesn't have any feedback mechanism for me, so it just looks like a confused dead robot in the middle of the street.
I think Waymo and Cruise are both happily working on hard problems in this space with limitless VC funding (or daddy GM money) thrown their way. So I support their efforts, because at the very least, they'll enrich our understanding of self-driving cars even if it were to fail in the marketplace long term.
I'm curious how profitable it will be in practice once the VC money dries up. Paying half a million dollar salaries to employees who need to keep these things up to date adds up. That, on top of hardware costs for precise sensors that will fail fast in harsh weather conditions. On top of normal wear and tear of people in and out of the cars all day for cars that won't need down time.
Lastly, I'll end my thoughts with this... why are we obsessed with the idea of self driving cars anyway?! What human problem does this solve? I am 100% on board with building autonomous cruise-control for my own car, so I'm not against the tech. I just find the taxi angle to be weird. All I see so far in my mind is a product that just takes away an entire class of job opportunities with no actual gain.
