Elon Musk has decided that the next step for Tesla Motors cars is to go (mostly) autonomous, IEEE Spectrum reports.

From the Financial Times:

“We should be able to do 90 percent of miles driven within three years,” [Musk] said. Mr Musk would not reveal further details of Tesla’s autonomy project, but said it was “internal development” rather than technology being supplied by another company. “It’s not speculation,” he said.
