A car that can only drive within major cities in the UK and on motorways would be entirely fine for the vast majority of people. Exceptional journies I can always rent a car that suits my needs for the one week in several years I'm in the Highlands.
People will abuse that. They will get high/drunk/whatever and when that “5%” rolls around (quite unexpectedly mind you), they’ll run into a bus full of nuns. Always assume people will be judgement impaired because “the car can drive itself”....
But, this is also why I think the next car manufacturer race will be about who can solve this for their customers. That is, who solves the problem of making 95% autonomous cars able to drive in 99.9% if all situations without manual intervention by the driver, where the provides automatic remote control from massive rooms full of people steering drunk car owners out of situations the autopilot couldn’t. The better the autonomy, the fewer people needed to remote override.
The value in the 95/95 autopilot is because it will make commercial drivers be able to never need breaks (they sleep or rest until the autopilot is in trouble, and they can even remote control cars). And of course because a lot of people seem to hate driving and would pay to avoid it.
I don’t - I hate owning a car.
