I tend to flee, also. Case in point, a couple days ago a state police car fell in behind me on the freeway. I took the next exit to "flee." He followed me off the freeway. I turned right and he turned left. I wasn't his target this time.
A policeman can follow you for a relatively short distance and catch you doing something to stop you for. I no longer take the chance. If one is behind me I park or change my route.
Yes, there are good cops and bad cops. But you can't tell the difference by looking.
