I don't know about saving lives,but every time I get behind a vehicle with a bad exhaust system I wish Florida had an E-check requirement. When someone in your car has severe asthma,these poorly maintained vehicles are a real problem.Edit to say I got behind 3 different,newish vehicles on the way to church tonight that we're putting out so much pollution I had to turn off the air. C'mon people, take care of your vehicles “Hell will be filled with people that didn’t cuss, didn’t drink, and may even have been baptized. Why? Because none of those things makes someone a Christian.”
