I agree, I ride a bicycle so I'm more aware than someone sealed in a car would be, and unless I'm not moving, I only hear loud motorcycles right as they're pass

I agree, I ride a bicycle so I'm more aware than someone sealed in a car would be, and unless I'm not moving, I only hear loud motorcycles right as they're passing me. The headwind from cycling at 32 km/h is enough to overpower loud exhausts in my experience.
