I might have jumped a crown vic cop car before, and it didn't trip the switch, if that helps. Oh ya, the trunk was open and slammed shut upon landing and still didn't trip it, and the switch on those is located in the trunk.
I went ahead and stopped by Autozone and got a sensor for a Ford Ranger (which I drive daily). I set the switch and moved it around quite a bit trying to set it off and the sensor didn't trip. The only time it would trip is if I banged it against my hand to where it made a sudden change in acceleration. So I'm going to give it a shot and see how it works out.
