As a New Yorker, with cars on the road I have a reasonable expectation of where they might be coming from or what direction they're headed (ie, they're following traffic laws). With bikes, they can (and do!) come from any direction, on the sidewalk, riding the wrong way on the road, wrong way in the bike lanes, etc. These bikes could be considered as motorcycles (ebike designation is a legal one), they often go 20mph or faster by delivery drivers with little consideration of pedestrian safety, and you really don't know where or how you might encounter one so your head needs to be on swivel as pedestrian in NYC.
That said, I'm still pro-bike and acknowledge that cars are much more dangerous for pedestrians, just I'd like to see the delivery bike / ebike problems fixed.
I think with e-bikes we've entered a new equilibrium that will take some time to shake out. It used to be that the fastest bikers on the road were usually the most experienced, this is no longer the case and as a street biker I have noticed it causing more danger.
Where I live e-bikes haven't caught up yet. I need to be mindful of that people get scared of me biking fast close to them on the sidewalk, even though I'm experienced and know that there's no danger. A bike without motors is enough steerable that it doesn't pose any real danger for anyone imho.
