These cars don’t even go onto highways or areas where accidents are more likely.
Accidents are less likely on highways. Most accidents occur in urban settings. Most deadly accidents occur outside of cities, off-highway.
Sure mile for mile they are less likely. But when they happen they are generally more serious as higher speeds are involved, and if Tesla has shown anything it’s a much more complicated process for autonomous vehicles to navigate and deal with edge cases (like vehicles on the side of the road, emergency or otherwise). Much harder (and dangerous) to just slam on the brakes and put on your hazards on a highway than a side street if the car gets confused.
I could see accidents being more likely for autonomous cars on highways though
For humans, but not necessarily for camera-based autonomous cars? They also can’t just stop on a highway to prevent accidents.
