Got my M3 in early February. I’m an avid bike rider and ride pretty much every day on the local greenways. I got an Allen bike rack for the M3 and it holds the bike securely and does not damage the car. With the rack and bike mounted on the car however backing up is a real adventure. The obstructed sensors cause the car to bark warnings constantly. While it stops when I change from reverse to drive I wonder if it is damaging the system. Anyone else have experience with this?
