. Officers are people too and they don't like dealing with jerks just as no one else does.
In my experience, more than a few officers are jerks, and I don't like dealing with them.
I haven't been pulled / waved over in a car, but have been when on a motorcycle on occasion over the years.
About 40 years ago I didn't say or do anything much….. Just sat astride my bike, accepted the speeding ticket (on three occasions) and carried on. I haven't had a ticket since.
About 30 years ago I was pulled over when I fell foul of a give way law that had been changed during a couple of years that I was abroad. I asked, "What's the problem?"
The WPC explained the law change and sent me on my way. Last year the law was changed back to how it was before. Now it is in keeping with the rest of the world again.
About 20 years ago in the UK I was pulled over, so once again asked what the problem was. The PC's said that they had seen my bike wobble at a roundabout. They got me to blow into a breathalyser, got a negative and sent me on my way.
I had felt the wobble, and suspected a problem with the rear wheel. On inspection when I got home I found the bearings had failed, so replaced them a few days later.
Where I live now, like many locals, I seldom bother stopping when waved over at the frequent checkpoints. There is no point….. I wear a helmet, carry a licence and my bike's registration is current. Better leave the police to deal with heinous criminal tourists who obligingly stop sans helmet and licence on a rent-a-scoot. In exchange for a fee of about $20 they get a document that allows them to ride without a helmet or licence for the rest of the day.
