Elon Musk: fully autonomous cars "in approximately 3 years"

I hope he's right (TechCrunch):

Musk is now saying that Tesla cars should have “full autonomy” in “approximately three years.”

As for when regulators are ready to sanction self-driving technologies, they “probably will not allow for full autonomy for one to three years after that,” said Musk. “It depends on the market. Some will be more forward-leaning than others.”
