The car that shows up already knows the route.
Waymo alone is running well over 250,000 paid robotaxi rides a week across a handful of U.S. cities, and Tesla is pushing its own version into more markets. The rides are already normal for the people who use them — no small talk, no tip, just a car that arrives, drives well, and drops you off.
The number that matters is cost: robotaxi rides are trending toward $0.25–$0.35 per mile as fleets scale. At that price, owning a car in a city stops being the default, and taking five short trips a day instead of one long one stops being expensive.
