1 - Tailgaters
2 - Horn honkers
3 - People who obviously have money yet wear jeans

But the biggest one lately:

People who bag their dogs poop, twist it up nicely in one of those poop bags,
and then just leave it there.

A disturbing trend lately.
We see them sitting on the side of nature trails.
Yesterday there was one on a picnic table in a local park.
In that one the specimen was rather impressive, a really big dog or maybe a homeless person?
