They're going about 15mph under the limit for no reason. I overtake & then he spams the high beams, constantly flashing.
I slow right down in case he's trying to warn me something has fallen off the car & he backs off. I accelerate & he's then spamming the high beams again. Then it's pretty obvious - he's just upset that someone overtook him & showed him up for being a slow arse while he's with his boyfriend.
