Today I got a tirade of abuse by a woman cycling on the right hand side of the shared path, because I was riding on the left and would not get out of her way.
Well, one does not know what to do, because they might swerve in my direction if they realize they are on the wrong side, or, like in this case, we might collide if they are convinced to ride correctly.
I normally stop before collision, obviously.
It is mostly tourists on city bikes that ride on the right, but this one was definitely local!
Once I witnessed the exact same: a rider showered another with abuse, this time the shouter was right, it was the other riding on the wrong side.
Another time it was a jogger that got sarky "which way are you going??"
Well, 'ya muppet", you are jogging into me, I'm where I'm supposed to be - did not say that of course

Again, on the quite narrow riverside path, a bunch of tourists on city bikes take the whole path.
When I politely suggested they keep to the left because there will be fast riders coming from round the blind corner, one says "do you want me to take a license to ride a bike?"
All right mate, get run into then

With this sunny weather the shared paths are busy, we must have a system ... or not?
Should we just ride slalom like, hoping for the best?
I don't think my cycling skills are up to this
