When I looked up back up sensors on google images, it seemed that the sensors on all the soccer mom cars were placed at the farthest back surface of the vehicle. If they're placed as described above, there will still be the lip below the sensors on the Camaro's bumper. I don't know enough to know if that matters or not, it's just an observation. I do know that there would be less conspicuous choices than to mount them next to the reverse lights, and I'm having a hard time working out the symmetry in my head of how that would look.
I realize it looks silly to a lot of people, but this might actually be a deal breaker for me.
