Cruising down I-75S just into FL about 1:30AM. Come over a hill and there is a LEO in the grass median. Just over the hill as my eyes catch him, full alert Ka on the V1. I think fack, I'm busted, but still out of habit nail the brakes (road was empty and had set cruise at speed and let right foot hover on the brake pedal in case of emergency like this). I know I'm going way to fast for him to be not interested in a stop, and I know he was interested in speed as he hit me with I/O radar from a hiding spot.
How long does it take to lock a speed in this sort of situation? Would there possibly be enough time to drop up to 25 or 30 mph before he could register a speed?
