I've taken to clearly saying which side I'm going to pass someone walking or cycling slower than me.
"Passing on your right"
I did it yesterday and got a very warm response from an older woman, who said it was a common expression in the US. She really appreciated it and wished other cyclists would do the same. Do other people do this?
There is a lot of mixed use cycle way near me and in Central London, I suspect much of the infrastructure vaguely promised will come in this form, rather than making roads narrower. So any other ideas for sharing with people walking? Hoping for a thread of ideas and suggestions =)
