Burger King figured out a way to turn a Tesla autopilot error into marketing.

The fast-food chain on Tuesday released an ad that uses part of a YouTube video in which Tesla's assisted-driving feature mistakes a Burger King sign for a stop sign and begins to stop.

"Smart cars are smart enough to brake for a whopper," the ad says, with an offer for a free burger if smart car owners post a photo at a restaurant location. "Artificial intelligence knows what you crave." 

The original video appears to be from a May 10 post on YouTube by "EV.network." In the six weeks since, it's only racked up a little over 1,000 views.

"Just as I come over this hill there's a Burger King sign that's down the hill, and it's going to try to stop," the driver can be heard saying. "'Stopping for traffic control, over and over again, and then it figures it out."

Tesla's autopilot is no stranger to internet videos showing its errors as the company collects data to improve the software. Still, the company's marketing materials and CEO Elon Musk's comments about "full self driving" have come under fire as misleading and dangerous.
