There's a problem in that the danger is in front but the exhaust noise goes out the back. I was once driving cross crunchy in a big truck with a trailer when I was startled by a loud motorcycle coming up beside me. He had been in danger the entire time he was next to me but I never heard him until he got right next to the cab. They should really point the loud exhaust forward but who wants to live with that noise?
