It is. And it's a nice feature that at least the luxury car makers are iterating on. The problem is that it isn't very interesting for folks who don't want to own a car and/or want a robo-driver to take them door-to-door all the time. A real freeway autopilot feature is still a nice convenience/safety feature but you still need a licensed sober driver for the endpoints of the trip.

much higher stakes and much less response time. There are plenty of city drivers that get confused and, well, pull over or even just stop. it's irritating, but a sensible thing to do.

On a freeway, that's terrifying.

It _seems_ like lots of parallel systems, each with the capability to reduce speed or stop could cope with city traffic about as well as a tourist. but, uh, I guess $2.5B says otherwise.
