95% of the value to me of self-driving cars is being able to sleep/nap on the way, so I'd agree with you that a slower trip is generally going to be more tolerable.
Well, given skyrocketing housing prices, a self-driving mobile home would be a perfect solution. Living in a vehicle by the side of the road is against the law but living in a vehicle that's always moving from place to place seems like it's legal.
