Also looks gorgeous in a car fire Seriously, why is it that gasoline vehicles are allowed to just store a big mass of highly flammable fuel in a tank, and that's considered to be good enough? Tesla went through great effort to develop a highly flame-resistant battery pack (cell isolation, active heat quench, passive heat quench, controlled pressure release, etc), and it shows. That was certainly a much harder task than storing gasoline in a way that will resist combustion in an accident. So why do gasoline vehicles get to get away with storing massive amounts of highly flammable fuel just sloshing around freely in a tank, in a manner vulnerable enough that there's a car fire in the US once every two minutes and which kills nearly 500 people per year there? Two cars out of every 1000 in the UK catch fire every year.
