Honestly they sit right next to interstate exits and scan people it will beep instantly if somethings a miss and its upto them if they want to investigate.
Is it for our safety or their benefit?
Just take it off when parked and put it back on when driveing. and if they are outside on public road. Open your trunk and drive for a bit. Say you "forgot" to close it.
Legally speaking if its a private lot they should not have any jurisdiction as they should only enforce public roads?
