YouTuber BaronVonGrumble has a veritable tantrum when he spots another motorcyclist wearing a suspicious vest.
The vlogger's anger is well earned as he gets closer and you see this biker who has reflective clothing looking extremely similar to one worn by police in the streets of England.
However, this vest proved very deceptive.
The other thing you can learn from this video is just how crazily all motorcyclists drive on the other side of the pond (as well as the other side of the road). In between lanes, around lanes, telling people gas caps are open, checking who's smoking pot, it's all a fascinating travelogue complete with a sizzling, acerbic rant.
