Only when I'm in their jurisdiction.
.... I.. used to drag race. A lot. Back before my two beautiful T-birds were totaled (the crashes were not race related, and funny enough, not my fault.)
The one thing I did learn from that experiance was to identify cop cars at a distance, and what city they were from. If they were across the lines, I have to admit we loved thumbing our noses at them.
I also learned how safely control a car going over 100 miles per hour.
Of course, when I do encounter a cop who could pull me over, I hang back to about 5 over the speed limit. For some reason I feel like I'm being dishonest by going the speed limit just because a cop is there. Never have been pulled over for it.
Personally, I like traveling behind
police cars. The ones around here go 10 to 15 over the speed limit, so it's one of the best places to be.
