Duh.

Spend 5 mins on the road in Missouri and you'll see 100 new cars go by with a scant trace of engine noise, and 1 1994 geo metro missing an exhaust, plastic wrap over one window, two doors of different colors, with the driver on a cell phone smoking a pack of Pall Malls, riding on 3 bald tires and a spare, with the rusted tail pipe spewing white smoke. They pull into quick trip and run inside for a bottle of oil so they can fill up the engine before they pump their gas.

Once again, liberal regulations new cars hardly solves any problems, but looks great for pleasing the voters of "blue states." ...sort of like providing tax credits for new home owners for energy efficient homes... Where apartment complexes have air conditioners from 1970 and the tenants pay the electric bills. All these regulations just add cost to doing business without providing any real benefit to the environment. But the regulations buy votes, so why not?

If we want this changed, we really have to start voting for science, which currently, neither party can associate with. Stupid stupid stupid.



In many states it's a largely solved problem, with annual or biannual inspections needed before you can renew your car registration. (along with the ability for police to site you if there's a visible or audible problem)

There are loopholes, though. There are fair number of trucks in my state that are allowed to run dirty diesel trucks with basically no exhaust protections. Their industries (construction? mining?) get some exemptions under the law, I assume. It's utterly stupid, as those trucks probably account for more particulate emissions than all the other vehicles on the road put together. But God forbid someone increase their "cost of doing business" by requiring some improvements.


How long does an old car with bad emissions have to last before it's worse than the environmental impact of replacing it with a new car?


There's also the energy cost and pollution of manufacturing a new car.


That's what I'm asking about.


The fact that 100 new cars go by without a trace is evidence that the regulations work, no?
