CT has had numerous problems with their emissions program(s). Whatever the Feds threatened to withhold in highway funds for not doing emissions, we've probably spent 3 times over on the emissions buildings, corruption, fraud & graft, and two complete overhauls of the system, in addition to the initial program creation. In essence, we have spent hundreds of millions to test if "check engine" light bulbs are functional.
So who fails the emissions tests? CT residents with poverty level incomes who can neither afford late model cars nor the funds to repair their older cars are forced by big bro to spend hundreds of dollars on an old smoker, then they can get a waiver. I would believe it's a tough sell to tell that father who failed emissions that his family is eating Ramen noodles this month is doing their part to clean the air.
Somehow, I fail to see how mankind is served by this process. I would imagine we've spewed more pollutants into the air on the drive to the test stations to pass already compliant cars.
