You can blame the electronics all you like but the truth is cars can have faults, both mechanical and software I once drove a Vauxhall Cavalier were a small wire had got in the way of the throttle input lever causing it to have a very high idle. If this wire had got in the way any further it would have caused the throttle to stay near wide open. If it had I'd have either put the clutch in (plenty of brake assist and power steering but the engine running unloaded at the rev limiter) or turned the ignition off (no power steering or assisted breaks) depending on whether I had a good straight bit of road to stop on or not.
