I was doing the speed limit, cop car charges towards me from quite a distance away and tailgates me. I sped up to prevent being run down and he turns on his red/blue lights (mind you, this was at night so it's harder to see that it is a cop car). I pull over, he comes over looks at the bike and asks "have you had any trouble with the police lately?" I said that this is my first ever. He doesn't even ask for my license, so I do because I'm late for work now. Hand it over and wait a few minutes, he comes back and tells me that the fine will be in the mail. The guy seemed a little unusual since he was looking at the bike and not me (and my bike is nothing fancy at all) or probably just looking to get one last fine in before the night's over. Anyway, what I'd like to know is if cops are allowed to "force" people into speeding similarly to how I did (I know I'm still at fault) and whether or not getting a fine in the mail is unusual?
