Drafting etiquette
When you are riding and some stranger passes you, is it ok to catch up and draft behind them? Is this considered bad manners? Or is there some proper way to do this that is polite? I do this from time to time without problem but the other day I did it and the guy in front slammed on his brakes so of course I slammed into him and both of us were very annoyed with the other. He did it on purpose because he thought I was a creep for drafting behind him. I had no idea this was not allowed. So what is the right way to draft behind a stranger when out and about?
