A4 Rally Racer

and I am driving up this 1 mile uphill road, when I look down at the speedometer and I am doing 75mph in a 45mph zone, then I look in my rear view and I this 50 is flying at least doing 90mph I stay calm and let off the gas, & don't tap my brakes since I am going up hill, and finally get down to the speed limit, I thought he was going to pull me over, but he came up in the left lane and smiled, then on my way home

the same 50 pull out of my residential street

thank good local police in PA don't have use of radar, I believe only state troopers are granted this right in Pa,
