BMW will double self-driving car testing fleet despite U.S. fatality

MUNICH -- BMW will not change its strategy on autonomous vehicle testing despite the death of a pedestrian struck by a self-driving car during tests by ride-hailing firm Uber, senior executives said on Wednesday.

BMW said it would double the size of its autonomous vehicle testing fleet to around 80 this year.

"Our estimation about autonomous driving technology remains unchanged even though this appears to be an extremely regrettable accident," Klaus Froehlich, BMW's board member responsible for research and development, said of the fatality.

"The path to autonomous driving is a long one. I have spoken about a mission to Mars," he said, adding BMW was conducting its own tests under a high level of security.

Froehlich said BMW's self-driving cars would undergo a test regime equivalent to 250 million driven km (155 million miles).

Of this, 20 million km will be on real roads, while a giant supercomputer will simulate traffic scenarios in a virtual test regime equivalent to 230 million km, Froehlich explained.

Self-driving cars will appear sooner if cities dedicate special lanes for autonomous cars in ring-fenced areas.

"In a dedicated space for only autonomous vehicles, it is easier to anticipate what other vehicles and traffic will do," Froehlich said. "This makes it easier to program vehicle reflexes and may even allow a car to have fewer sensors and less processing power than a vehicle which needs to navigate normal traffic with things like bicycle couriers."

BMW plans to launch an autonomous vehicle in 2021. Introducing a vehicle earlier than this is not plausible, since chipmakers and software designers have not yet developed a computer capable of processing the sheer volume of data generated by a self-driving car, Froehlich said.

BMW is preparing for a new era of on-demand mobility where customers locate and hail vehicles using smartphones. Ride-hailing and car-sharing could be replaced by fleets of autonomous cars, once self-driving cars are roadworthy, Froehlich said.
