So how do these new engine related serious crashes happen then where the
electronics are tweaked to make it unable to stop?

IIUC, these "bait cars" they use in the US telly programmes are tampered
with so that they can be stopped by remote control when the thief drives off
in them, I'm sure someone with the relevant skills could do something
similar to make the car unstoppable. I know my car has various "drive by
wire" stuff like the throttle and the semi-auto gear box which are
electrical rather than mechanical. I had a hire car with a push-button
ignition a while ago, so a simple over-ride of that part of the circuit
means you wouldn't be able to turn the ignition off either.
