Edward t,

I disagree, the circumstances that you describe are only one of many that may invoke shutdown of the unit in the event of an impact. Consider a few of the following, 1) Unloading pallets from a powered conveyor such as in a bottling plant, operator gets it wrong , has an impact and truck cuts out with the forks in a pallet on the moving conveyor. 2) Truck goung across railway lines too fast, impact cuts the truck out, 3) Same crossing a road, hitting potholes, 4) Run down a grade and trap someone up against a wall or other obstruction....there are other forseeable scenarios. If you are happy to put people in tghese circumstances at risk, as these are"VERY suspicious" arguments, I hope you can sleep well at night!
