As a city dweller I got rid of owning a car in 2015. Now I just hop in someone elses car using a ride sharing app if I'm going a short distance. If I am going a long distance I can rent someone elses car, either from a company that owns a fleet or from an individual using Turo / GetAround.
In SF you can rent a car to drive somewhere using Uber's GetAround integration for as little as $8/hour. Crazy.
