Its a Freeway Reconnaissance Person. This is the person that flies by you when you are already doing 80 on the freeway, thus going ahead of you searching out would be speedtraps and taking one for the team and getting a ticket so that you can push past still doing your 80 MPH..
During my morning drive on the 405 freeway, my normal F.R.P. flew by me doing at least 100.. I saluted him and knew my morning would be ticket free..
