What it really comes down to is that the large majority of drivers on the road today just do not check the maintenance on their cars regularly. They don't check air pressures, fluid levels, lights, ect. This nitrogen is just another way to make a lazy people even lazier. Just look at the other cars on the road when you are out driving and see how many cars and trucks have visibly low tires. When they come out with an oil that leaks out slower than the current oil so you only havee to check it once a year, I'm going to hang up my wrenches.
