For how many of those 46 minutes do you think they are enjoying control and adrenaline? I would guess approximately zero, and once you tell them that they can spend that time instead surfing the internet, or eating breakfast, or videochatting with their family, they will.

When autonomous cars are ubiquitous, the price of insuring your thrill ride will be roughly equivalent to the hourly price of an amusement park.
Long before "automonous cars are ubiquitous" something else is going to happen - automatic collision detection and prevention will become ubiquitous, long before all cars are fully automatic. So even if I drive the car myself, it will be very difficult to crash, therefore the insurance will have no reason to increase.
Either way, I am sure fully automatic cars won't become ubiquitous in our lifetimes no matter what manufacturers say, so I'm not too worried.
Any transit system I've ever used was:
Over crowded.
Purposefully designed so no-one could sleep. Also, I really wouldn't want to sleep on an artificially created publicly shared surface.
Frowned upon to talk on your cell phone, or eat a meal.
I definitely couldn't get any work done, even if I tried.
(hi; I live in a city run by "fiscal conservatives")
This is exactly what makes autonomous vehicles so great - they eliminate the public transportation problem.
The bus is not a great place to do any of the things mentioned above.
But this is a great illustration of self-driving cars: it's public transit for the upper-middle class. (The middle class can't afford a reliable car for the whole household; the rich have chauffeurs.)
