Michigan not only have vehicles that shouldn't be on the road, but the air pollution is horrible! If the state of Michigan do vehicle inspections, the air levels would drop dramatically. Consequently you have a lot of vehicles driving around on the road that spew noxious gas that, in many other states, would be entirely unacceptable. Vehicle inspections ensure that cars will be regularly examined for their safety and suitability to stay on the road. I do care about air quality, and having to drive through a cloud of black smoke just because people won't have maintenance on their vehicles makes me angry. Another issue Michigan have is registration tags being stolen off plates. I'm constantly paying for new tags. I shouldn't have to cut my tags just so someone won't take it. If Michigan allowed windshield stickers, and car inspections, things would be a little better.
