Seventy years of sprawling suburban development makes cars the most practical way for most people in the U.S. to get around, but actually owning that car may become optional.

Roughly 18 percent of Americans have used a car-sharing service, WardsAuto columnist John McElroy said during a panel at the 2014 SAE Convergence automotive electronics conference.
He also said that 60 percent of Americans are aware of Zipcar and ride-sharing service Uber, despite both companies and the services they peddle being relatively new.
On the other hand, McElroy said only 40 percent of Americans are aware of Kia--a claim that may bruise a few egos at the Korean carmaker.

Automakers are also getting involved in car-sharing themselves.
Mercedes-Benz parent Daimler supports Car2Go, which operates a mixed fleet of gasoline and electric Smart Fortwo minicars in several European and U.S. cities.
Perennial Mercedes rival BMW operates its own DriveNow service in Europe as well as San Francisco employing ActiveE electric cars.
Those ActiveEs were previously used in the pilot program that laid the groundwork for the current BMW i3 electric city car.
