"<a href=""https://www.youtube.com/watch?v=nl1tZx9knzA&amp;t=5m21s"">5:21</a> LOL", I find it funny that the company that Tesla hired to install their roofs independently is doing a better job of it than Tesla. Then again, they started out as a specialty roofing company. Tesla: Not exactly the best at anything. Batteries maybe. Rockets perhaps, but there was clearly a pretty steep learning curve there. Sometimes ambition moves faster than technology though. Or good engineering.
