Level 55 rear view mirror glasses-suggestion for game upgrade

I just achieved level 55 and now have the rear view mirror glasses. Beside a different look to the Avatar, that’s all that it is (like most any other reward). But, what if like level 50 fire socks (that leaves a trail of fire when you go at or above 150% FTP), these glasses actually allowed a PIP window (say, at the lower left corner) that showed what was going on behind you. Would be a very cool look. Could offer some fun perspectives during racing, etc. You can toggle between views already, so we know a rear view exists, but what about adding it in a small window, as if you really had rear view mirror glasses on? Would be very cool and a reward to definitely level up for.

hahaha, I am past level 50 and didn’t even know there were fire socks… I never pay attention to the avatar LOL
