>> On this speedway, students and entrepreneurs are racing to the future. I'm Peter Henderson from Reuters at Thunderhill Raceway about two hours North of San Francisco where a lot of self driving cars are in a race. The race is really just to get around the track quickly or at all, rather than going too fast.
In fact, if there are too many people in a car, the speed is capped at 35 miles per hour. But these are a lot of small companies, basically little startups, that are trying to understand how to make their cars work in real world situations that are difficult to try in the real world.
Many of these companies can't test this on a street, where there are people walking by. Or if they wanna push the limit of what the technology they can do, they definitely don't wanna do that on the street. Here, they've got a two mile track. They can try new things.
Some of them may work, some of them may not. You also have students at an online university Udacity who got six weeks to put together some software to run a car that has been going around the track here. They haven't quite made it all the way around without having to grab the wheel, but they have managed to make a turn or two and they're making it better and better as they go along.
All cars competing had a driver behind the wheel to lend a hand if necessary and out of the nine self driving cars in the running, only four made it around the curvy course without human intervention. Today It's a very laid back situation, a lot of engineers having fun and trying to push the limit of what a car can do.
