That’s just what NVIDIA CEO and co-founder Jen-Hsun Huang did in his opening keynote at the 2015 GPU Technology Conference. Just moments after announcing NVIDIA’s DRIVE PX self-driving car computer, he sat down for a quick fireside chat with Musk, who, as usual, put the pedal to the metal.
“We’ll take autonomous cars for granted in quite a short time, ” Musk told a crowd of some 4, 000 at the San Jose McEnery Convention Center. “I almost view it as a solved problem. We know what to do, and we’ll be there in a few years.”
Musk—who also is co-founder and CEO of Space X, has floated an idea for an ambitious system of pod-like transports, and recently compared the development of artificial intelligence to “summoning the demon”—made it clear that NVIDIA’s advances in GPU technology will play a key role.
“What NVIDIA is doing with Tegra is really interesting and really important for self-driving in the future, ” said Musk.
Not that Musk thinks autonomous cars will come easily. It’s a long road to get from developing the capabilities to implementing them. For example, he predicts that regulators will be loathe to allow self-driving vehicles until they’re presented two or three years of compelling evidence about their safety in comparison to driver-controlled vehicles.
Musk also cautioned that we’ll eventually will have to embrace a seismic change in our relationship with cars as regulators struggle with how to transition from driver-controlled vehicles to those controlled by computers.
“In the distant future, (legislators} may outlaw driven cars because they’re too dangerous, ” he said.
He also noted that while getting autonomous cars to cooperate at 5-10 MPH is relatively simple, doing so at speeds between 10 and 50 MPH in urban and suburban settings—with pedestrians, cross-traffic and a host of other obstacles and distractions—will prove to be the really hard part of the work. Beyond that, he said, “Once you get above 50 MPH in a freeway environment, it gets easy again.”
That’s not all. Musk said that the transition to autonomous cars, even once they’re ready for prime time, isn’t going to happen overnight. He noted that there are 2 billion cars on roads today, and that the auto industry is cranking out another 100 million a year. At that rate, it would take 20 years to replace that fleet if autonomous cars were available tomorrow.
“It’s not going to all transition immediately, ” Musk said. “It’ll take quite a while.”
And then there’s the matter of security. When Huang asked him for his outlook on that, Musk said the threat of hackers taking over cars becomes more significant only if the steering wheel and brake pedal disappear. Until then, drivers can override any potential problems with their hands and feet.
But all these concerns have done nothing to dampen Musk’s view of self-driving cars as a near-future inevitability.
