We have a huge population of delivery drivers on ebikes (and also elec/gas scooters). They ride on sidewalks, against traffic and constantly run stop signs and red lights. They're not just a danger to pedestrians, but also creating an awful risk for themselves (I just saw one hit by a car next to Barclays in BK this weekend).
I'm an avid biker and have slow rolled my way thru many stop signs, but I've never put myself or other pedestrians at risk in the manner as many ebikes riders do.
The NYPD has ignored this problem, as they do most quality of life issues in the city. I'm not sure how we resolve it but there does need to be dialog among everyone to fix this issue. This is not just an issue of car vs. bike, its an issue of pedestrian safety too.
