Musk commands a lot of respect from me. He understands that money is a means, not an end. In other words, he uses money and makes money, but his goal is to make the world a safer, more affordable, more luxurious, more fun place.
I was listening to an interview of him and he mentioned something that intrigued me about autonomous cars. They're ready, he said, but we as a society have to decide what level of fatality is acceptable. Whenever you or I drive a gasoline car, there is a nonzero chance of an accident (and a fatality). So, what does that chance have to be for autonomous cars for them to be acceptable? I personally think the technology will be here soon, and then revamped laws will follow. I'm hoping my next car will be an autonomous Tesla!
I watch a lot of his interviews too. Gives me a lot of insight as to the really important things in life and the changes that he is working on. Fully autonomous cars will be here soon and only the law has to catch up, which it will, taking its own sweet time.
