A lot of people have hypothesized that autonomous vehicles will drastically change the economics such that daily car sharing/rental will be cheaper than car ownership, and similarly convenient. This might in turn lead to a decline in car culture and personal car ownership. With a larger percentage of vehicles being owned by companies (or at least by individuals who are often loaning out their vehicle to the network), the distinguishing factors in the market may shift away from personal taste and lean more heavily on efficiency and safety and gadgetry.

A lot of hypothetical guesswork in there of course, but those are the kind of ideas I've heard lately on the matter.

What model of car was the last taxi you took? Did you pick that taxi because of its stylish design? In contrast, were you impressed that the driver knew a shortcut to avoid traffic by getting off one exit early and going through a parking garage?
