In case you haven’t heard of Waymo, it’s a Google-owned autonomous vehicle taxi company. If you’re in Austin, Phoenix, San Francisco, or Los Angeles, you can have a Jaguar F-Pace with tons of sensors and radar technology pick you up and take you to your destination.

Waymo reports thousands of smooth driverless rides per month, and a majority of rides go without incident. In Los Angeles, however, Waymo’s been in the headlines twice within two weeks. First was when Mike John became trapped in a driverless taxi going in circles.

This time around, it’s more of a Waymo-is-the-hero story. On Saturday, January 4, the LAPD responded to a Waymo passenger’s call about a man attempting to steal his ride. The man wasn’t trying to ride for free, though. He jumped into the driver’s seat and tried to take the Jag for a joy ride.

However, his attempt would be in vain. Waymo’s driver’s seat is programmed with a weight sensor that determines when someone is sitting in it. During normal conditions, passengers are not allowed to sit in the driver’s seat for safety reasons.

The only people allowed to operate a Waymo car are company-approved drivers. Police were surprised to see a drunken man sitting in the driver’s seat after the car’s security system alerted them. The man was able to get in when a passenger unlocked the car with his phone to start his ride.

A Professor says the thief certainly got schooled

Despite being autonomous, Andrew Maynard, a professor at Arizona State University’s School for the Future of Innovation in Society, says the company is in control “at all times.” Therefore, the thief just made himself look bad.

“That means it’s almost impossible to steal a [Waymo] car,” he explained to CBS. “What amazes me is how quickly Waymo was able to respond with immobilizing the car.”

Waymo says the cars can take the wheel on incidents like these, too. Waymo cars can honk, use evasive maneuvers, or it can warn people outside of the vehicle that authorities are being notified.

“I think, more than anything, it shows us that Waymo has a very secure system,” Maynard continued.
