You have the wrong gas. The stuff in diesel exhaust is not laughing gas. Here is a quick reference from the EPA. "Nitrogen Dioxide (NO2) is one of a group of gases called nitrogen oxides (NOx). While all of these gases are harmful to human health and the environment, NO2 is of greater concern." https://www.epa.gov/no2-pollut...

There are standards for emissions because emissions are bad. When companies cheat like this, society as a whole suffers. They should rightly be punished. VW cheated by up to 40 times the NOx limit set. People have their lives shortened from air pollution. Here is the New England journal of medicine saying people exposed to pollution 'disproportionately' caused by diesel are as bad as a pregnant woman smoking: https://www.nejm.org/doi/full/... Let's be clear - VW willfully exposed people to this pollution to make additional profits. We shouldn't let them off easy. Clean air is good for everyone, and should be fought for. What is wrong with people thinking it's no big deal because they like there cars!? We knew lead was bad and it took the US multiple decades to get it out of products, we are making the same mistake again.
