Tesla CEO Elon Musk said last week that his company is close to developing software that can perform fully autonomous driving.
Recently, however, one Tesla customer posted a video showing how the company's Autopilot software mistook a Burger King sign for a stop sign. The fast food chain turned the clip into a social media ad.
The video shows the Tesla slowing down and flashing the message "stopping for traffic control" as it nears a Burger King alongside the road. The software eventually ignores the sign and resumes driving normally. "Happens every time I drive up this road," the customer wrote on YouTube.
"Smart cars are smart enough to brake for a Whopper," Burger King said in a video on its Twitter account. "Artificial intelligence knows what you crave."
It offered a code for a free Whopper to anyone who posted a picture of their Tesla at one of its restaurants using the hashtag #autopilotwhopper.
"So first we have to spend $100,000 on a car to get a free whopper?" one user replied. "Trust me, if I had money to buy an autopilot car I wouldn't be eating this."
The customer who posted the original video later added an update saying that the next version of Autopilot was no longer confused about the Burger King sign.
"Good learning, Tesla," he said.
