Tesla has shown off a preview of an upcoming ride-hailing feature in its app ahead of an August robotaxi unveiling. The company released mock-ups of the upcoming feature, which showed the ability to "summon" a ride from the Tesla app. The company didn't offer many details about how it would work, but images show Uber-like functionality, with the ability to remotely set the car's temperature ahead of its arrival. Tesla CEO Elon Musk announced earlier this month that the company would unveil its long-promised robotaxis August 8. Tesla has been promising a self-driving ride hailing service for years, with Musk promising the company's robotaxi would start picking up riders back in 2019.
