It will not. In the NYC metro area (including Northern NJ), pedestrians are constantly in danger of being hit by both cyclists and people on powered bicycles (which are motorcycles for all practical purposes).
I have seen these people hit people and on one occasion one of them kicked a stroller. If anyone says anything, they face further harassment: In one instance, one rider lifted her bicycle and hit me and left.
Delivery drivers tend to be better than others on the sidewalk, but then you watch them go the wrong way at 30 MPH with the giant battery pack and you feel for the driver who might have a close encounter or worse.
Sidewalks are for pedestrians.
PS: I notice that this thread seems to be full of people who claim standing on the sidewalk watching cars whizz by is scary. It isn't. Cars don't routinely jump the curb, cars don't routinely drive on sidewalks, most drivers are quick to yield to pedestrians. On the other hand, even if you are crossing at the walk sign, there will be at least four bike riders trying to run the red light through a hundred pedestrians at 42nd & 8th.
