E-tests are in fact the WORST.

Cars will never cause as much pollution as the factories situated here do, yet they are not limited. Logging companies, coal power plants, nuclear plants (Three Mile Island incident where the situation was played down and let the people get irradiated until the evacuation order was given), etc..

List goes on and on. Stopping car pollution isn't even beginning to solve the problem.

You could try running the car on nearly pure methanol, maybe to pass the emissions test.
