saw someone doing the oxford to cambridge last year on a supermarket special with wrong way round forks. didnt have the heart to tell them, by the time I came across them theyd done 60 miles and had probably got used to the handling.
scariest thing I saw was a guy commuting in oxford, riding with his bars at about 45 degrees (as if he’d fallen off, twisted them around the fork and not realised they could be straightened). the look of concentration on his face made me want to be there when he had to suddenly react to something.
ive given up pointing out wrong way helmets, its usually on kids with their parents (and occasionally their parents) and they look at you like your a paedo for taking an interest in their child’s welfare.
