Why is it transformative? Especially in cities. You have Ubers/taxis/private cars/etc. today. So you hypothetically cut the costs (maybe) in half of hailing a ride. Which is speculative. Does that really transform your use of transportation? I doubt it would change my use of cars one bit.
There are tipping points. If always taking the taxi everywhere is more expensive than the cost of owning your own car, then most people drive their own cars and taxis are for special occasions. If after a tech change always taking the taxi everywhere is less expensive than the cost of owning your own car, then most people would do just that, and only a minority would own a car.
A switch from 20/80 to 80/20 is transformative, changes the default attitude and has further societal effects.
Like parking or more specifically - not parking. Here's an example development: "And parking clocks in at a full 29% of the developed land here, taking up twice as much total space as the actual buildings."
Parking may be reduced but the flip side is that we will have hoards of always cicuclating cyber cabs or we’ll have private owners returning and summoning their private vehicle from free parking at home, thus doubling the trips taken
Not to mention sending a car out for errands. Self driving will free up parking garages, but fill up the roads.
