While driving on hway around 2am ish on a weekend (soon after last calls), i noticed a cop speeding around 80ish without lights on and without any read on my RD. then i noticed him pulling someone over that was in front of me (i was going at limit, luckily). so i was wondering:
do some leos use their own car's speed to catch speeders (ie. slow their car when they meet up w/ a suspected speeder, and if the other car's going faster and over the limit, then pull him over)--altho i'm not sure if it's even admissible in court.
i saw the leo finish up in less than a couple of mins (the time it took me to catch up with them), so i'm wondering if it's more for sobriety reasons the leos speed on the freeways like that.
