Sometimes I do suspect the more gear-oriented riders seem to judge other riders by their gear, and if it doesn't measure up to a certain standard, the rider I isn't worthy. The guys in lycra don't often wave at me, I think because I don't dress like them. But it's hard to tell what goes through their minds.
Except my shorts were lycra and while my jersey was wool, you would only know that if you read the label. And considering my bike was oriented parallel to the road, I was behind fiddling with the chain and they were coming up from behind, they didn't know what I had nor what the problem was.
No, these guys were just d-bags with no particular motivation.
