Here's an interesting question: how many injuries have they had from open outside doors? And how would dropping propulsion prevent the injury when the train is moving at 79mph? I've seen many conductors open a door and lower the trap while moving in order to make a station stop short, as well as highball before raising the trap and securing the door. I've also see a SL lounge door pop open at track speed because it wasn't properly dogged shut despite being closed. In which of the three scenarios here would this door protection circuit help matters? Answer: NONE.
Some days you get the feeling some of these rule makers have never left their cube in 20 years, and are perhaps little old ladies.
All you're going to do here is add 30 second to every low platform stop in America as well as create once/week delays where the circuit won't work right and a train will sit in a station for 10-15 minutes while we putz around trying to figure out which door is or is not shut, what sensor is bad, can we get permission to cut it out... I can't wait til a cold morning at 6am in Grand Rapids or Port Huron in January when one of those sensors freezes open and the train can't leave the terminal until they cut the car out or get a mechanic.

Finally, for my coup-de-gras-de-stupidity, compare the amount of injuries from open doors (once a very common fixture on commuter trains) to those from grade crossing incidents. We have 'em every day, a few deaths per week, WE DONT DO S*** ABOUT IT other than painting cute "operation lifesaver" logos on a few boxcars.
I give up. You cannot be this stupid and make it across the road in the morning. You just can't
