That.....suuuuuuuucks. Sort of hypocritical that you were pissed at a guy sitting in the bike lane, while you were exceeding the speed limit by 15 mph though if you think about it. Although it's pretty funny that you honked at a cop haha.
I have to question whether a cop can legitamately sit in a bike lane (which is illegal) and clock people. I tend to think situations like that are BS. And in that vein I still don't get what the horn ticket is for. In my view (aside from you speeding) it was fair to honk at someone parked in a bike lane because that's not safe. Just because it happens to be a cop, I think it's BS that he can give you a ticket for honking at him.
Btw what does the machete have to do with going to Hawaii, you realize you can't take it there with you, right?
