I'd have thought that even 1000 Amps, let alone 10000 Amps, at 12 Volts across one's torso would be enough to instantly kill someone, and even fry them.
And it can't be that the current flows for only a nanosecond or something, because presumably the current must last a fair time to turn over a large vehicle engine.Work in the public sector? Read the IR35 FAQ hereComment

Mains 240v is dangerous because, at this voltage, a few mA (milliamps) will pass through the body.
It is true that current (i) is what kills, and you don't need much current at all, but you need a high voltage (v) to overcome the body's resistance (r).
i = v ÷ rScoots still says that Apr 2020 didn't mark the start of a new stock bull market.Comment

It's like shooting a building with a gun, voltage is how piercing it is, amps is how much damage it does if it gets inside
Without enough voltage the amps can't get in so no damage
Another example, hold multimeter probes in each hand, measures 0 (or almost 0), current through the body
Stab the probes into each of your thumbs however, and you will die instantly because blood conducts electricity rather nicely
