The idea is that if enough people use ride sharing, the total number of cars needed will decrease, therefore, the needed space to put those cars will decrease. It doesnt necessarily require that everyone use it, but its about reducing the total number of cars necessary. If the density of these cars are sufficiently high, I can see a world where not owning a car is more convenient than owning one (if it isnt cost prohibitive).

This was the claim of ride-sharing about 10 years ago but studies showed the opposite, that it actually increased congestion.

Clean, effective, prompt, affordable, quickly constructed mass transit however, does seem to work.

I'm not anti-robo-taxi or pro-mass-transit. Instead, if the value is fewer cars and less carparks, mass transit with the aforementioned properties has been shown to work.

Sadly the United States has been unable to hit those notes with their projects (LA's metro, for example, is still constructing approximately the Prop A system approved by voters, in 1980, 44 years ago: https://upload.wikimedia.org/wikipedia/commons/thumb/6/6f/Lo...) so in that specific case, it's murkier.

That world and system exists, its called public transportation and Europe

Even in europe a lot of people do own cars. If you have a friend network that really works you can manage without (we share two cars between 5 drivers), but realistically extremely cheap rideshare would be better for us in the long term (we lucked out on a deal with a car dealer who closed shop in a hurry, but now the cars are 12 years old and it start to show, even sharing the repair bills)

Elon’s highly individualistic. I feel like his communal car-sharing society vision is at odds with that. How will that dialectic resolve?
