Elon loves to rub it in the haters' face. Just to piss off the short sellers, Tesla is introducing a new clothing product called Tesla Short Shorts! That plus all the volatility over the last few days in the Tesla stock performance, has gotten the short sellers so mad, they're actually suing Elon. Also, Elon has promised to open source his Tesla security software to the rest of the car industry. The goal is to make future cars as hack proof as Elon thinks Tesla's are.
