Ride sharing could also mean fewer vehicles on the road and, crucially, taking parking spaces. Today, even if I had a car, I would not use it. Why? Because there is no place to park. The last couple times I tried driving a car at night, I spent double the travel time, just crawling around the streets near my house until I could find an open parking spot. After the last time, I vowed: never again. With self-driving, it gets better. When driving is a monetary transaction and human-powered transportation is free, then I expect that people will feel less impulsive about just taking a quick drive. With other necessary trends in human-scale urbanism, I expect that means the small children will just have to bike themselves to their friends’ places.
