Here's a lot of places where pedestrians and cyclists share the same walkways, maybe it's the same where the other commenter is from? It can definitely be a problem of infrastructure; even ones biking without electricity often go waaayyy too fast for it to be safe at all.

I walk with my dog a lot and almost every day there's a situation where some crazy cyclists flies past us like 30km/h and doesn't even ring the bell. If I had a more reactive dog it would be a nightmare, a lot of of dogs are triggered to chase if something "runs" past like that, even if they're super friendly and wouldn't actually do anything if they caught the "prey". I don't understand how the cyclists don't care for their own safety even if they clearly don't care about others; if a bigger dog lunges at them (which is almost impossible to prevent with zero warning time, even if they dog was held by the collar) they're the ones that could fly to the asphalt from high and hard. I'm surprised more small children aren't hit by bikes as well, since the cyclists don't seem to slow down for them either.

And yes cars are often a problem as well and the crosswalks can be horribly unsafe because of idiots driving, but at least here the cyclists too are causing constant danger to pedestrians - because of the bad desing. Even without ebikes bike lanes are a must just as roads for cars are
