It’s sensible to ride on the left.
Riding along a cycle path (not next to a canal) around a blind bend, guy coming towards me. I’m towards the left but move right over… and he moves across to his right! So smash, we both end up on the floor. He was a bit larger than me so went down a bit harder, rolled around on the floor and moaned a bit.
If we did convene to ride on the left, it wouldn’t have happened, and I did say that it might be an idea to start doing so
