I've no affinity towards reckless, or inattentive riders. And it's a shame that guy hit you.

But I must have a different concept of rudeness.
And I've been recently socialized into the habits of always shoulder checking, always signalling, and always trying to look out for the other guy, or at least check if he's there. Even if he's too slow, old, fat, or sugar depleted to do his share of the pulls.

But maybe this populous little country wouldn't work so well if people didn't make such efforts to be sociable.

And that other bit: I was just having a bit of fun. I remember what it was like to be fast. You do get to know who everyone important is, even from a distance.
