You dont need a direct line to the hardware if you’re just forcing bit flips through a large magnetic field. That’s why they hook to the frame; it’s the largest piece of metal.
You’re not hacking a car via fault injection alone though. You can probably crash and reboot the ecu, but there’s no way you’d manage predictable control over which bits you’re flipping.
Also because ground on a car is so dirty, the electronics are well isolated.
If you have any evidence of this actually being possible, I’d love to read it.
