Elon Musk says that self-driving Teslas are on the way. In an interview with the Financial Times, Musk declared that his electric car company, Tesla, is officially in the race to bring autonomous vehicles onto the streets — a race that Audi, Mercedes, Nissan, Volvo, General Motors, and Google are already in. The CEO tells the FT that he believes autonomous Teslas will be able to operate largely, but not completely, on their own. “We should be able to do 90 percent of miles driven within three years,” Musk says. However, a vehicle that can operate without a human in the cockpit isn’t something he thinks is feasible.
