This happened to me today which kind of spoiled an otherwise awesome day's ride. I was hoping someone could shed some light on it and whether they've had a similar experience. I was riding home today after a long ride when this fool in a silver Camry starts dragging me off at the lights, swerving into my lane and braking and generally behaving like a dangerous fool. I did what anyone would do...I split through traffic as fast as I could and left him behind. He was swerving in and out of lanes to keep up, but either got stuck in traffic or gave up. Anyway, I pull up at red light when I hear this angry voice yelling, "Pull over! Pull over now!" I turn around and see this angry dude in a 4X4. So I turned left down a side street and pulled over...thinking if he is a cop, I don't want him chasing after me. So I pull over, he gets out and starts yelling and swearing at me saying, "What give you the right to ride like that?" and "Just because we're not in uniform doesn't mean you can do whatever the f*ck you want"...and stuff like that. I asked him if he was a cop and he said yes. Taken aback and not knowing whether he was a cop or just some random, angry nutjob I figured the best thing to do was calm him down by going into a 'yes sir, no sir, three bags full sir' routine and told him I will ride slower in the future and that I was sorry and blah blah blah...basically I bullshitted him in the hope that he would chill the f*ck out, get back in his car and piss off. He tells me that he was about to call the Croydon police and have a divvy van sent to pick me up and a truck to have the bike impounded. I spun him some more 'I'm sorry, I'll ride slower from now on' bullshit and he got back in his 4X4 and left. Now, I know everyone will say, "You should have asked to see his ID, and asked him what his name was, his rank and where he is stationed" and I know this. But at the time I was a bit freaked out and didn't know if I was talking to a really angry off duty cop or just some random psycho who hates bikes. It was unpleasant to say the least. it just freaked me out a bit is all. First I have to ride like a maniac in heavy traffic to escape some dickhead who is trying to run me off the road, then I get yelled at by an enormous, furious dude who may or may not have been off duty popo. So my question is, what's the deal with off duty cops pulling you over and has something like this happened to anyone else?
