On your left - to me means someone's going to pass me on my left and I should hold steady and not veer left.

however, typically by the time it's shouted at me, I'm confused, I look around and I probably veer left. I've found myself doing that on bike paths. Luckily, i don't bike on trails much.

It would have been nice if the guy gave you room to pass - but if you were in a car and there were 2 cars driving the same speed in front of you in 2 lanes - you really wouldn't go up behind one of them and honk & flash your lights until one gave way. (Yes, I know some people do that...)


So I'm sure the guy didn't like being passed by you for whatever reason - and what he did the 2nd time was definitely uncalled for - but the first time could have just been ignorance of what you wanted him to do.
