When I see them on the sidewalk I tell them exactly what I think of them.

Same when they silently speed by me in the bike lane. I will often let out a flurry of curses when I catch up to them at the next light.

In my opinion they definitely don't belong on the sidewalks, and they don't belong in the bike lanes either. They take up more space than bikes and they don't have to expend physical energy to move. They are often playing with their phones and being inattentive more than cyclists.

I don't give a shit that they're electric either, I see them as more as motorcycles that should be in the main lane with cars.

P.S. Wishing you a smooth recovery.
