They should be banned, imo. Well, the ones without brakes, certainly. They are a menace.
Sadly, with more and more cyclists on the roads, we’ll see more and more idiots too. Same as with car drivers. Most are just crap drivers, but some are downright dangerous.
Personally, after making sure the bloke was ok, I’d have bawled him out there and then for being a dick. Maybe a bit of public humiliation mightuv made him realise his actions aren’t condoned by others, and that he just looks an idiot and gives the rest of us a bad name.
If he’d bin wearing silly clothes, I’duv given him a good kicking as well for good measure.
