Blimey! It seems like you have problems in the States that I never encounter. A couple o years ago, I passed a Gypsy horse and trap; the driver decided to race me. The clip clops became faster, and I wondered what hw was going to do next.
He drew alongside; and told me good things about the horse pulling said trap. We were fast approaching a blind corner, so I drew back a bit and let him go. Yes, I had had enough! But he was right. Pony and trap combination can be a fast one!
But a couple o` days ago,. I had a race with a 14 (or so) yo lad who was with his pals. I managed to ward off any overtaking he attempted; never realized the old legs still had it. Then followed the language. I wondered "Why?" and then realised.
He had been shown up in front of his peers . . . . to coin an old English expression "They don`t like it up `em . . !
I guess I`m pretty fortunate where I live. There are loads of cyclists who even have kids in a trailer behind the bike. Not good imo.
