or, just follow my suggestion and give your neighbor a little beat down. I hate nazi's who can't control their own lives so they go around enforcing.
Kinda like this fella that I saw on courtTV... he's not a police officer, but he goes around in his SUV on friday and saturday nights performing "citizen's arrests" of folks he thinks are drunk. He videotapes all this stuff from his dashboard with a home video camera, that's where it gets funny. He sees a guy in a 80's camaro cross the center line on the highway then follows him to the gas station, blocks his car in and waits for the guy to get out of his car angry "Why are you blocking me?" dude tackles him and yells "this is a citizen's arrest, you appear to be driving under the influence sir. Stop resisting, I've already called the police"
The dude in the camaro was much smaller, but still managed to run off and call the police on his own to report the crazy fella who tackled him.
That was the most extreme case as the fella wasn't drunk at all and the fella tackled him to the ground, and the police got called twice. ;-) They showed quite a few other videos he had made where he managed to videotape a few folks weaving on the road and call the police, not sure of the results.
If somoene doesn't have anything else better to do than meddle in building codes or weaving motorists all weekend long...maybe I should have pity for them, nah.
