The state's "Highway Design Manual" has guidelines for building MUPs, including minimum widths to avoid conflicts, especially for cities with lots of pedestrian use. None of the ones I use come anywhere near these guidelines. So yeah, I go slow and I "ding" from way behind. 2/2

I think the ding from way behind is key. Gives plenty of warning, less likely to startle, gives people time to process the info. I really dislike people who grunt a sweaty "ONYERLEFT!" into my ear when they're already half-wheeling me (group rides excepted, when such behavior is expected.
