2 motorcycle cops work Research Parkway and Austin Bluffs, through to Powers, most often westbound. Watch out because they try to nail you coming down the 45-mph marked Research Parkway at the bottom of a large hill, where gravity will be making your car go >45 mph. They work in pairs and hide on the small side streets, with radar guns. Again, Westbound on Research near Rangewood to Austin Bluffs, watch out for 2 motorcycle cops.
