I live in a weird semi-rural not-a-township so my laws may seem petty compared to others because my "town" is generally governed by the county/state.
No idling automobiles for more than 60 seconds. Drive or get off the pot.
Leash law for dogs and cats (currently we have neither)
Ban on all wood fires, both inside and out (I'm sick of choking on other people's fire smoke every time I go outside, we already get that enough from wildfires)
It's in the same vein as point #3: because of inversion effects and occasional wildfires, we often have mediocre air quality. As mentioned, this is a semi-rural area, where you'd think "peace, quiet, and fresh air," but we don't have those things because of constant noise and/or air pollution from idling vehicles, lawn mowers, leaf blowers, barking dogs, bonfires in summer, wood stoves in winter, burn piles all year round (they get SO smokey when damp, which due to the climate is 75% of the time), etc. So it's a general quality of life thing for exercising/working/relaxing outside (and because we're such a small community, outside activities are all there is to do around here, unless you drive to the next town over). Furthermore air conditioning in rare in my neighborhood so we rely on open windows on hot days, which means inviting all those unpleasant sounds and bad air inside.
However, I have a personal reason why the car idling issue is especially bothersome. One of my neighbors insists on idling their car for 5-10 minutes every morning before work. They leave between 5-7am (way before I wake up) and their driveway is right next to my bedroom window. So in summer I either have to a) boil alive with the window shut or b) get woken up before dawn by the sound and smell of their car exhaust. I've also witnessed people watching videos or chatting on the phone in their cars outside the only entrance to our only park while their car idles for god knows how long.
Throw in the occasional dog attacks (because of #2, we have loose, poorly-trained, unsupervised dogs wandering the streets), and it's unnecessarily uncomfortable trying to stay active and touch grass around here. So considering what little purview our town has, those are the things I'd change.
Unfortunately* that's not much of an issue in my area, which means people feel comfortable starting their car (remotely, even!) and leaving it running while they do something else inside. Out of sight, out of mind, and next thing you know it's been twenty minutes. Maybe gas is actually too cheap...
*It's ironic that low crime rates have a downside! Because generally this is a great thing
Nothing against you, but as someone from the rural southwest, I cannot see any level of compatibility between your gripes and rural life. It’s like some from NYC complaining about too many people around.
