Tesla owner says his app unlocked a stranger's car — and let him drive off with it

• Tesla owner Rajesh Randev says he accidentally drove off in someone else's Tesla.

• He said that the Tesla app granted him access to another man's nearly identical Model 3 sedan.

• Tesla did not return a request for comment about the strange incident.

Using a smartphone as a car key for your Tesla has many perks. It means one less thing to carry around and lets you conveniently unlock your car, hop in, and drive without ever turning a key.

Sometimes, you can even jump in and drive somebody else's electric car, according to Canada-based Tesla owner Rajesh Randev.

Earlier in March, Randev got in his white Tesla Model 3, which was parked on a Vancouver street, and drove off to pick up his kids from school. The only problem: He didn't actually get into his own white Model 3, but rather a nearly identical one parked next to it, he told The Washington Post.

After about 15 minutes, he started to notice unfamiliar things about the car he was driving, like a crack in the windshield and a missing phone charger, he told the outlet. As he sees it, his Tesla phone app granted him access to someones else's Tesla, he told the paper.

But that's not all. The glitch appears to have worked in the opposite direction, too. The other Tesla driver involved in the mixup was able to unlock Randev's parked car using his Tesla key card, according to the Post. That way, he was able to find Randev's phone number on a document inside the car and inform him of the snafu.
