What I don't understand is why people find this situation so hard to belive it's possible. We've seen computer freezes/hangs for 70 years. Why is it so impossible to belive that an ECU can freeze too? Before you say "watchdog", remeber that the watchdog needs to be reset by the actual "gas pedal" execution thread to work, and not by anything else that may still be running while the "gas pedal" thread is stuck/crashed. Also remember that an ECU needs to be specifically instructed to cut the gas/power after a reset, not assume that the car was off and it just booted normally.
