Cars are going to undergo a lot of changes in the coming years.

One of the biggest: You probably won’t own one.

Thanks to ride sharing and the looming introduction of self-driving vehicles, the entire model of car ownership is being upended—and very soon may not look anything like it has for the past century.

Drivers, for instance, may no longer be drivers, relying instead on hailing a driverless car on demand, and if they do decide to buy, they will likely share the vehicle—by renting it out to other people when it isn’t in use.

Auto makers, meanwhile, already are looking for ways to sustain their business as fewer people make a long-term commitment to a car.
