Funny the bay area complaining about Tesla's hazardous substances when they don't mind human waste classified as a biohazard on the sidewalks. There's no money in cleaning up that, though. Tesla needs to abide by regulatory laws, joking aside.
It seemed crazy to me that Tesla chose among the highest cost, highest red-tape area to open up shop.
