Not even close. It's a 2-ton vehicle that can self-drive reliably enough to be roving a city 24/7 without a safety driver. The measure of expensive for that isn't "can everyone afford it", the fact we can even afford to let anyone ride them is a small wonder.
I’m a bit confused. If we’re talking about consumer cars, the end goal is not to rent a car that can drive itself, the end goal is to own a car that can drive itself, and so it doesn’t matter if the car is available for purchase but costs $250,000 because few consumers can afford that, even wealthy ones.
b) If there was a $250,000 car that could drive itself around given major cities, even with the geofence, it would sell out as many units as could be produced. That's actually why I tell people to be weary of BOM costs: it doesn't reflect market forces like supply and demand.
You're also underestimating both how wealthy people and corporations are, and the relative value being provided.
A private driver in a major city can easily clear $100k a year on retainer, and there are people are paying it.
