Elon Musk's self-driving evangelism masks risk of Tesla autopilot, experts say

Tesla's ambitious futurism has earned it loyal fans - but after the death of a driver using autopilot, some say the company should be more explicit about limitations

Elon Musk's rockets usually do not stray beyond Earth's orbit, but that hasn't stopped him from making promises about Mars. The Tesla CEO's wild, ambitious futurism has earned him billions of dollars, fawning coverage from the tech press, and a subreddit devoted entirely to discussion of his divinity.

But it has also now landed him and his company in the awkward position of explaining why a feature they called "autopilot" should not be to blame for failing to prevent one of their vehicles from driving under a truck in May, killing 40-year-old Joshua Brown - the first known fatality involving a self-driving car.
