A shill?
A math novice?
More likely just a fanbois, willfully ignorant of the fact that gasoline ICEs can and do often have small fuel leaks that don't present any danger.
On the other hand, 400 volts @500 amps is potentially lethal regardless how small the leak is.
Anybody watch F1 (Grand Prix) auto racing? In 2014 they switched to a hybrid engine format with an energy recovery system charging supercapacitors, which are like storage batteries on steroids. Because of the stored electrical charge, when the driver exit the vehicle he has to jump off, leap into the air so he's never in contact with the car and the ground at the same time. Otherwise he could be in danger of the supercaps coupling to the ground through him and frying him to a crisp.
