Devoted to the auto industry – builders to enthusiasts

Have car, no driver required.

General Motors Corp., executive announced Monday cars that drive and park themselves could be ready for sale within 10 years.

According to an Associated Press article, much of the technology already exists that will allow the vehicles to operate, radar-based cruise control to lane-changing warning devices.

Rick Wagoneer, GM's chief executive, will discuss driverless cars as part of his speech Tuesday at the Consumer Electronics Show in Las Vegas.

In a recent interview with AP, Larry Burns, GM's vice president for research and development, said "This is not science fiction."

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.

"Now the question is what does society want to do with it?" said Burns who added tests of driverless technology would likely begin in 2015.
