The radar issue is one that I think is probably real but with the exception of the front windshield probably not all that much of a factor in actual practice with maybe the exception of a cop being on your backside. I have thought the best way without be one of the detectors with external sensors.
As far as 15% to me the issue would be if you are setting yourself up for getting pulled over more often and then getting a ticket depending on the local regulations dealing with transmission. You could always borrow if needed for something like the airport. Some of the airport regulations deal with where the car is parked and how the passenger pickup and delivery is handled.
