Driverless Cars Could Soon Rule the Roads

Cars that drive themselves -- even parking at their destination -- could be ready for sale within a decade, General Motors Corp. executives say.

GM, parts suppliers, university engineers and other automakers all are working on vehicles that could revolutionize short- and long-distance travel.

The most significant obstacles facing the vehicles could be human rather than technical: government regulation, liability laws, privacy concerns and people's passion for the automobile and the control it gives them.

Much of the technology already exists for vehicles to take the wheel: radar-based cruise control, motion sensors, lane-change warning devices, electronic stability control and satellite-based digital mapping. And automated vehicles could dramatically improve life on the road, reducing crashes and congestion.
