Self-driving cars aren't just for people who don't want to drive, says Elon Musk. They're also for those of us who don't want to do all the annoying stuff that goes with driving, like walking to the parking garage or squeezing into tight parking spots. 

The CEO of Tesla and SpaceX said Sunday that drivers will ultimately be able to use Tesla's new "Summon" feature to call their Model S and Model X cars to wherever they are from across the country. The recently released software update allows Tesla vehicles to park themselves on command.

"Ultimately you'll be able to summon your car anywhere ... your car can get to you," Musk was quoted in The Verge as saying

The entrepreneur and technologist said last month that Tesla's cars would be able to drive themselves within only two years time. He has described the task as easier than people imagine. 

"I think we have all the pieces, and it's just about refining those pieces, putting them in place, and making sure they work across a huge number of environments--and then we're done," Musk told Fortune last month. 

His bold predictions don't mean the cars are ready just yet. Key to achieving these goals are more sensors. 

"You need a lot of redundancy ... more cameras, more radars, redundant power buses ... so that any system can fail in the car and it doesn't need to backup to a driver," Musk was quoted as saying during a call with reporters. 

And even once the technology is available, there's a question of whether drivers will be ready. Tesla has decided to restrict availability of its semi-autonomous "autopilot" driving feature after videos of drivers driving without their hands on the steering wheel in dangerous situations surfaced.
