Last weekend a couple passed me and a friend while we were passing a jogger. They were completely silent.
I caught up to them and said “I am on your left, I say that so you know I am here. You passed me while I was trying to safely passed that jogger, you unsafely passed me and put all 5 of us at risk”.
The woman responded “thanks for the advice” I couldn't really tell if she was being sarcastic or not.
When I was growing up, we were taught to say in a non-startling way “on your left” or “on your right.”
Even some signs with bike etiquette might help or posters in bike shops. People are ignorant AND arrogant.
im training 20miles 4 times a week for my endurance rides,a kid launches and passed me on his high speed bike and i tried to get patient about his disrespecting...but like i was expecting,the kid pull over after a minute catching his breath...i yelled at him “run out of breath aye! SUCKS! thats all you got”...and if he passes me again on my training...il tail him till he blows his lungs this time...
