It is no different than operating a vehicle on a roadway. You are supposed to leave 2 car lengths between you and the car in front of you. If a car cuts in front, and they will (jerks), you have to slow down and add two car lengths again.
Or
Don't. ...and be too close and run a higher risk of a rear end collision in which you are almost certainly going to be found liable. Tailgating while hyper aware sorta works, but emphasis on hyper aware.
Same thing with running a (smaller) vehicle on a sidewalk. Yes, it is going to be painfully slow to be safe. No, you cannot drive faster safely. No the pedestrians don't have a responsibility to look out for you any more than the car in front of you on the freeway has a responsibility to look out for the tailgater.
There is no right of way on a sidewalk. So it is 100% liability to the rammer. Sure, a pedestrian could rear end a sidewalk vehicle. But in that scenario the pedestrian is ramming, and is at fault.
People walk into each other all the time too. Fortunately people are usually soft, squishy, and flexible. Injuries happen, sure, but add a vehicle (not squishy or flexible) to the mix and it gets real dangerous real fast. Kids and old people have issues just walking in the same places (kids are the problem in this scenario), putting some of them in vehicles expands the issue.
Sidewalk drivers have zero right to demand, or even expect, pedestrians to look out for vehicles on the sidewalk. That is dangerously flawed logic.
Oh, posh. Of course when you are walking you can't see what is behind you and if a careless ECV driver is going too fast and plows into you, it is their fault.
However, I still maintain that you should be aware of what is around you and you should watch where you are going..
If you are facing the side taking a picture, fiddling with your backpack, or talking to someone and you back into a scooter passing behind you at a reasonable walking speed, is it the scooter driver's fault? Or how about in sardine crowded conditions you step in front of, or suddenly try to cross in front of, a scooter, is it the scooter driver's fault if you are bumped? In those type of conditions everyone is moving along like a giant wave and there is little to no space between anyone; scooter or pedestrian..It is continuous start and stop and just about impossible to predict what all of the people around you might be going to do. You are down below their eyesight and they don't see you. Shouldn't they take some responsibility to be aware of what is around them?
On a normally crowded walkway I am usually following a family member and before we can go 100 feet, at a minimum,four other groups of people have gotten between us. My family has to stop and wait for me to find a way to catch up to them.
I think what gives me indigestion from reading your posts is that you are lumping all of the safe, careful drivers in with the small percentage of idiot drivers. Plus you are taking a rather simplistic view of what a person in a scooter faces while driving in crowded conditions.and making everything their fault. You keep equating scooters with cars on a highway and, at least to me, that simply is not a valid comparison.
I have needed a scooter for approximately ten years, have used it to see Las Vegas and Broadway shows, been at the Rose Parade, arena shows, driven on the sidewalks of NYC and on the DC Mall as well as Disneyland, Walt Disney World, both Universals, other amusement parks, festivals and State Fairs and have NEVER run into or bumped anyone. I am well acquainted with crowds and know what I am talking about..
, I can only repeat---please give the careful, responsible drivers a break instead of wanting us licensed, regulated, segregated and, in some minds, eliminated.
