I was recently riding home from an 18 mile almost all off-road trip to a nearby town. Was just coming into the village on the main road and was tired, so just trundling along.
I was in the Trance X and wearing all the modern kit, carrying a Camelbak etc, and I became a tempting target for one of the locals to overtake at all cost. Mid 50's, out of shape, feet flat on the pedals of his elderly £89 Argo special. He came whizzing past, doubtless chuffed thinking that I wax in the "all the gear, no idea category".
Actually, I have a lot of idea (I'm a MIAS L4 quali'd MTB instructor) and knew he'd never take the oncoming corner at the speed he was doing. And he didn't, lowsiding and coming off as he tried to lean into it.
I trundled past, visually checking he was awright as I went by, and he'd dropped about 9 points on the cockiness scale is as baby seconds.
Point is, don't get hung up on what some other muppet is doing. Chill, let them get on with it. In our hero's situation I'd have pulled over for a swig O's water and let them bugger off. Not gonba have a coronary over a couple of muppets.
