Tesla CEO Elon Musk has said for some time that autonomous-drive vehicles are coming, but even he admits those cars will still need a driver behind the wheel.
Last year, he told the Financial Times that 90 percent of driving could eventually be handled by autonomous-drive cars. Beyond that would be a stretch.
"My opinion is it's a bridge too far to go to fully autonomous cars," Musk told the FT. "It's incredibly hard to get the last few percent."
In the meantime, it's fun to imagine.
