these are mounted in the back of @scrmblr404 (insta) mustang, they are part of the quiet racing club, im guessing they are some sort police countermeasures. the image is from a reel on @rly.slo apologies if this is the wrong sub but i feel that this community has the most diverse info on anything mounted on a rack
Yeah basically these night racers alongside those “QUIET” and “GHOST” crews run in packs at night without valid plates & if they encounter police they just turn off headlights, drop a gear and disappear, all for IG clout
