For crying out loud, the criteria is RIGHT there in the FREAKING NAME!

I don't get it. I see teslas on the road almost daily here in the frozen north. I can only imagine there's more in warmer climes and where there's more luxury cars on the road. They have some of the highest customer satisfaction levels for any car. They flat out outperform the competition in many regards. He built a better mousetrap, but instead of a mousetrap it was a multi billion dollar project to launch some of the most complicated consumer hardware people can purchase into an extremely mature competitive environment.

Whether or not Tesla survives or wins in the car sector, other manufacturers have been forced to respond to the market disruption.

Calling him a failure seems like an ad hominem attack, really.

While learning to fly full scale airplanes it was drilled into me over and over, it is *always* the pilot/operators responsibility.

You either screwed up, or failed to ensure you were using reliable equipment, or failed to account for uncertainties in how you operate it.

Running what is essentially hobby hardware (radios, speed controls, batteries etc.) over top of people is just plain irresponsible.

"Oh, but I haven't crashed before."

Yeah, until you do.

The 400' exemption in the FARs is *specifically* for hobbiest use. Commercial use is plainly not 'hobby' use. The National airspace system, and all the craft operating within it, and the FAAs authority to regulate its use do not magically start at 400 feet.

Does the golf channel realize that commercial use of UAVs is illegal?

Anti-scientific 'ban everything' movements are the flipside of the pro-CO^2 believers. People who think they intuitively know more than those who study that field in particular who have research to back up their claims.

It's a failing of our education system that more people don't understand science, the concept. You don't need to understand all the branches of science. You just need to know that 'my kid complains of headaches at school' does not mean you can pin the blame on WiFi without any further tests.
