I'm not sure I understand the logic of not offering a backup-camera option on the coupe. Both cars share all of the electronics. Why would a camera be available only on the sedan as an option?

My guess would be the location of the backup camera. On the sedan, the license plate is mounted high on the back of the trunk. However, on the coupe, the license plate is mounted low on the bumper. I guess Honda figured a camera mounted in such a low position on the coupe would be ineffective and chose not to offer the option. I'm sure with enough ingenuity, though, it could be fitted onto the coupe somehow.

I can totally see your reasoning, however, to get a better FOV (field of view), all you need to do is change the angle of mounting the cam and/or the lens. Once I get the coupe, I'll have to investigate aftermarket options.

Its def doable, you will need to just mount the cam in a custom area where it might not visually appear right.

You can change the angle, but the defeats the markets purpose of the rear cam. People think its to look back, when in fact this is not true 100%.
