He followed me from a student housing complex for several blocks before "hitting the blues", when I had stopped at another apartment complex to make a delivery.
As I returned to the truck, I muttered to myself "What's this a$$h*le going to do, give me a parking ticket?"
When he finally asked me "Do you know why I pulled you over", I looked him in the eye and said, "No, not really!"
He proceeded to tell me that because my son (aged 12 at the time) was with me, and the door was open, that he was in danger of falling out and getting hurt.
I asked him if there was a law concerning it, he said no.
I snatched my license from his hand, bid him goodbye and went about my business....
Pity you chose to react as you did.
A few years back, I was driving, in a bad mood, to a Drs. appointment, when I saw a cop on a bike pull out behind me. Swearing, I quickly put my seat belt on, but he came up alongside and motioned me to stop. I accelerated which is a dumb thing to do against a bike. He just caught me up and I had to stop. When I wound my window down,and spat at him I had to get to the Drs. he sat with his hands in his lap and said:
"When I drive behind you, I can see your front wheels are off side. This is called crabbing, because your front end is out of alignement. You should get it fixed, because it costs you money. And next time, put your seat belt on before you see me, not after. That'll save you money too. Good luck at the Doctors" And took off to my laughing "Thanks".
Sometimes they really are just trying to help.
I always bucked wearing a seat belt, but did it lot more after that.
