Mine is a 2006 Matrix and never gave it a thought to not drive it.
I had a GM vehicle lose throttle control when the throttle linkage broke off and the throttle went to full. I was approaching a T intersection and just put the car into neutral and turned off the ignition.... no problem.
This was part of my basic training when learning to drive and I think that it should be a part of mandatory emergency procedures.
On a Deisel, other than Common rail, the injector pump is powered mechanixcally by the engine, and "pulling the rack" shuts off injection, stopping the engine.
A "common rail" deisel uses a high pressure pump and electric fuel injectors, just like a gas engine (although much more robust) so shutting off the electricity to the injectors OR the pump will stop the engine if the pump is eectrically driven.
Most non-common-rail diesels have either a shutdown motor or an emergency kill linkage, or both. If the shuddown motor fails, you need to manually "pull the rack" to shut it off - which is what either a normal mechanical shutdown or an emergency kill does.
An engine on a large "loader" - Front-enf loader, Loader/backhoe, industrial loader tractor - whatever you want to call it - kinda like a 'Dozer with wheels instead of tracks.
I'd have thought hat someone with that training would know what to do. Sad results from an alleged professional with some driver training.
