Seen in rush hour yeaterday, from the elephant and castle to going over westminster bridge..A 30ish year old man hanging on to the back of a very large van! he had online skates on, it look a perilous journey, but hey ho at least he was not bombing along on the pavement. All the vehicles following him were saying rather naughty words to him, such as' old bean desist from doing thtat' lol
I'd quite often see that behaviour when I was still driving a Black Cab.
It wasn't just guys on skates, you'd see cyclists doing it too.
I've even had them hang on the side of the taxi.
To discourage it I'd slowly drift to the left, so that eventually it was either they hit the kerb, or let go.
