Dave I tend to disagree with you there. If I'm conscious fuel pumps stop by me killing power through battery isolation and if unconscious they'll stop on a dead engine. If engine is still running then the stewards pulling the remote isolator will kill engine and fuel.

In the case of a jammed wot u got a millisecond to smash a kill switch close to your hand. Manual kill switch to ignition will stop the car before you hit the wall not once the inertia switch feels the impact or an engine runs out of fuel even though the pumps dead.

Just how I run my car and I respect others opinions may/will differ.
