This is neat. For several years, Google heavily invested in efforts to build driverless cars, with a separate subsidiary named now entirely focused on it. Turns out, Google founders Larry Page and Sergey Brin lured a high-profile autonomous car expert to the company at a driverless car race way back in 2005. The catch? .

, Page attended the driverless car race the 2005 DARPA Grand Challenge in disguise so he could check out the scene without being bothered. That’s how they came across Sebastian Thrun, the eventual leader of Google X (which created the program now known as Waymo). At the time, Thrun was building a driverless car to race in the DARPA challenge.

Here’s more from the story:

“My team turned out to be the lucky winner for whatever reason,” Thrun told CNBC in an interview for the new series .

“And we got the attention of the Google founders. Yeah. So Larry came to the race itself and … came disguised with, like, a hat and sunglasses so he wouldn’t be bothered by everybody. But … he had a keen interest in this. Larry has been a believer in this technology for much longer than I even knew. And so was Sergey. And they really want to understand what’s going on.”

Waymo’s self-driving efforts have been in the news lately thanks to , alleging the ride-hailing giant is using stolen autonomous tech designs to pursue its own driverless car ambitions. A judge to halt potentially all of Uber’s self-driving car program as the case proceeds.

But back to Thrun. In 2007, CNBC says he approached Google about helping the company build its now well known Street View. Google took him up on the idea, and “...we built up Street View and with a singular vision to photograph every street in the world,” Thrun told the news outlet.

And it all started with a wealthy tech guy dressing in a disguise. That’s definitely an interesting way to woo a prospective employee.
