Look, no hands! Test driving a Google car

dangerous, Dolgov says, so its autonomous car can go up to 10 mph (16 kph) above the speed limit when traffic conditions warrant.

‘NOT A TOY’

In addition to the model I tested – and other such adapted versions of conventional cars – Google also has built little bubble-shaped test cars that lack steering wheels, brakes and accelerator pedals. They run on electricity, seat two and are limited to going 25 mph (40 kph.) In other words, self-driving golf carts.

Google’s isn’t the only driverless car in development. One of the others is just a few miles away at Stanford University (where Dolgov did post-doctoral study.) Getting the cars to

recognize unusual objects and to react properly in abnormal situations remain significant research challenges, says professor J. Christian Gerdes, faculty director of Stanford’s REVS Institute for Automotive Research.

Beyond that, there are “ethical issues,” as he terms them. “Should a car try to protect its occupants at the expense of hitting pedestrians?” Gerdes asks. “And will we accept when

machines make mistakes, even if they make far fewer mistakes humans? We can significantly reduce risk, but I don’t think we can drive to zero.”

That issue, in turn, raises the question of who is liable when a driverless car is involved in a collision – the car’s occupants, the auto maker or the software company. Legal issues might be almost as vexing as technical ones, some experts believe.

Self-driving cars could appear on by the end of this decade, predicted a detailed report on the budding driverless industry issued late last year by investment Morgan Stanley. Other experts deem that forecast extremely optimistic.

But cars with “semi-autonomous” features, such as collision-avoidance radar that maintains a safe distance the car ahead, are already on the market. And the potential advantages – improved safety, less traffic congestion and more – are winning converts to the autonomy cause.

“This is not a toy,” declared the Morgan Stanley research report. “The social and economic implications are enormous.”
