Like any law/rule, it generally comes about from ppl that misused/over-did the existing standard, we only have ourselves to blame........ As far as trying to mod the car for louder or more performance, the manufactures have pretty much done a good job to work within the the scope of our laws(Calf excepted).
When I had my Jeep, I had some Piaa 80w fog lights wired to be activated independently from my other lights, which is not legal in Va., But if I cover them when taking them in for the safety inspection that's excepted.
I'm inclined to agree with you, but am not a climate expert, which they seem to disagree with each other as well.
That is one way of doing it but is could get out of hand depending on how many mods you've done to your car.
The weather occupation is the only one you can never be right in and still keep your job
When I lived in Virginia, you could stick your hand out the window in the inspection station and give right/left signs instead of having lights. For a horn, all you needed was a bicycle-type bulb horn on the exterior of the car. May still be that way, I dunno. But it worked for me on my barely street legal dirt bikes.
I don't see Californians marching on Beijing, Mumbai, Moscow, etc. Remember trying to see the Beijing games through the smog? and they couldn't hold the rowing events because of the polluted waterways?
I will say this, my wifes family is from Mexico and when we go visit the air there is a lot cleaner than ours. Still its not bad here either. I had no idea Beijing was that bad.
Thanks for correcting me then. I thought it was still pretty bad in some of the cities with thermal inversions. I'm glad it's not bad, because Mexico is a naturally beautiful country.
Hmm, where we go is called tarandaquo (i think). There the air os clean and its actually a pretty place.oops. just went to wikipedia and looked under smog. not so good for mexico city . . . sorry. it's trapped in a thermal inversion.
Mexico City, Mexico
Situated in a valley, and relying heavily on automobiles, Mexico City often suffers from poor air quality.
Due to its location in a highland "bowl", cold air sinks down onto the urban area of Mexico City, trapping industrial and vehicle pollution underneath, and turning it into the most infamously smog-plagued city of Latin America. Within one generation, the city has changed from being known for some of the cleanest air of the world into one with some of the worst pollution, with pollutants like nitrogen dioxide being double or even triple international standards.[14
Same in NJ. My car even passed with HIDs.
