> as electrical systems are easy to work on and diagnose compared to mechanical systems. I'm not sure I agree with that. ICEs have a culture of DIY repairs. Sure, that could develop around electrics and hybrids, but HV electrical systems are dangerous. I'd say they are much more dangerous than ICEs.

> HV electrical systems are dangerous. I'd say they are much more dangerous than ICEs. Everything is dangerous. Gasoline is a volatile liquid carcinogen that bursts into flames when exposed to temperatures that numerous parts of the vehicle operate at, unless it evaporates first, in which case it explodes. An ICE engine block weighs several hundred pounds and can crush you to death. If you repair your brakes or steering improperly you may first discover it as your vehicle sails through a red light at a busy intersection or swerves out of control into oncoming traffic. If you stick your hand into a fan or belt and then it starts moving, you may no longer have a hand. Or an arm. Or enough remaining blood to stay conscious and call for help. There are ten thousand ways for idiots to kill themselves. But most people are not idiots, and have a strong personal incentive not to get themselves killed, which means that none of them are a justification for prohibiting people from repairing their own property.

Have there been any deaths from EV electrics? Most of them operate around 400v, which isn't super dangerous (touch it, and it might kill you, but there's also a good chance you'll survive). They also have far more protection subsystems than a typical house or factory. For example, if you cut into a high voltage wire in a car and touch it with wet fingers, the battery contactor will disconnect before you can touch the other wire to cause a fatal current.
