I’ve seen this twice now in the last year on sports running smaller axle’s and some other noticeable differences. I just feel kinda sorry for them and If they wave, I will most likely just lift one pinky finger off the wheel.
If your that hard up to find the “posers” look under their rigs for scrapes, scratches and tail pipe damage. It’s a dead give a way and maybe you won’t lose anymore sleep over it.
