Loud pipes especially some are obnoxious, just today I went the gas station with a buddy before playing some disc golf, some one was riding by and we had to stop our conversation and wait for him to get a block away before resuming it cause his bike was too loud to be heard over, if I can get pulled over for having my head phones in cause I cant hear an emergency vehicle, then mr loud pipes should get a ticket for himself not being able to hear and all the driver on the surrounding block too. As far as helmet go, would helmet laws save lives? Sure. Do I pay $200-1000 for my car to come with seat belts? No. Personally I think it'd be nice to see a bike/helmet combo packages. If I buy a helmet and Bike at a dealership, take the price of the helmet off or a percentage of it if its too expensive. Sure, some people would take the helmet and trash it or sell it, but even for the 1 in 10 riders that think, wow I got a free helmet, might as well wear it, it would be worth it. Basically I feel that it comes down to theres no way to reward/punish helmet wearers or none helmet wearers, so the only people to ride with one are the ones with common sense.
