The air is cleaner than 25 years ago - even with what you mention going on. BUT that doesn't mean the bi-annual smog check most cars have isn't a burden on the little guy too.

When we do away with the "visual" inspection BS and test a car based on what comes out of the tailpipe for that year vehicle only is when I will agree with it.

I'm all for clean air, but not the goobernmental BS that comes along with the testing we are doing now.
