Tinkering with an electric car when you don't know what you're doing will kill you so much more easily than a gasoline car will. That probably has something to do with it?
Alternatively, disconnect the steering column and drive off a cliff.
There are a thousand easy ways to kill yourself making uninformed modifications to any motor vehicle, by its nature. Its a ton of steel that goes up to a tenth the speed of sound. If anything, the reduced complexity of electric vehicles gives you fewer vectors for wrongdoing to screw yourself over. You can break any number of parts in a combustion engine to make it fail, whereas in an electric vehicle all you really have is steering column + drivetrain + battery pack.
It's much easier to intuit the risks from a mechanical danger than an electrical one. It's the difference between breaking a mechanical linkage and accidentally brushing up against a live terminal.
Seems that the chance of death from a gasoline explosion is much greater than an electric shock (of which a gas engine also has through smaller wires traditionally over longer runs).
I've definitely had my share of gas spills working on cars and boats. There are also very high voltage sparks going on. Then a gasoline car has several moving parts w/ vibrations while electrical motors are relatively vibrationless (assumes less chance of vehicle falling on you).
