Self-driving vehicles

Do you think this timeline is possible? From ABC News:

Quote:

General Motors Co. expects to carry passengers and deliver goods with self-driving vehicles in big cities sometime in 2019, telling investors it's moving quickly and plans to be ahead of other automakers and tech companies.

Quote:

....it expects "commercial launch at scale" of the autonomous vehicles within the next year or so. The vehicles would not have a human backup driver, the company said.

When I think of the many problems faced by car manufacturers (exploding air bags, ignition problems, etc), I just don't see how they can expect to have a driver-less car on the road within a couple of years that is reliable in safety.

To me, this is a timeline full of :eek::eek::eek: !
