As it started me and a couple of friends were driving down a highway for a bit, then there was a huge screen of what appeared to be smoke,but as we got closer the smell of exhaust got into the car.After driving through a couple blocks of exhaust,it turned out to be someones car that really needed a tune-up.The exhaust was coming out of the exhaust pipe,up to the trunk and down the highway leaving a trail behind it.I couldn't take a picture of it but this one is pretty close to what I saw...
