If you medically need them, that's different. So long as you can safely drive the things. If you would rent a traditional wheelchair were scooters not available (like pre 2000's), you're very likely legit.
After the end of the long day, all of our legs hurt. Our knees ache. Our backs are stiff. Our ankles crackle. Our toes and heels get blisters. Our crotches get red from where the underwear rubs all day. If any of those ailments are the medical reasons you are referring to, you don't need a scooter. You want one. And that is what I would like banned.
Add to that bus line cutting privilege (and the 4-1 bus capacity consumption), and you have another good reason.
Ok, by that rule, I don't
NEED one, I want one, it makes everything much more comfortable for me.
It's just much easier to use an ECV than to walk with my two crutches and my prosthetic legs (yes both) that I have needed since birth for the many miles that are needed to tour the parks. Except for my crutches, just looking at me, you cannot tell I have the prosthetics. I did this for many many years, not wanting to be a "scooter user" and abuse the system or get special treatment - I was always told that I was just like anyone else - so I sucked it up, took the pain - I took care of my blisters, was constantly drenched in sweat, handled all of the issues that arose from my prosthetics on a nightly basis and iced my hands every night to reduce the swelling. I waited in line like everyone else. Stood on the bus so that women and children could sit. One year a friend convinced me that I would enjoy the parks much more if I used the scooter, and she was right.
Are there people that abuse the system? Of course, any system is abused.
Do they have an unfair advantage over everyone else? NO - it all balances out in the end. There is no line cutting for rides, we enter and load for most as you would. When we do get separate loading areas, they are in the back, or the very front - not always the best seats. I don't ride many Omnimover rides because I don't want them to stop them. You see the ECV "privilege" in going to the front of the bus line, what you don't see is the fight that we need to go through when we need to get through a crowd. Do your feet get stuck in the tracks on main st? Do people stop in front of you and you are helpless to turn and move past them easily? Those who can walk can easily side step - ECVs cannot. It takes us 2 to 3 times as long to leave a park in a crowd - so when we get to the bus, the line to the front (besides being needed for loading purposes) is just an equalizer, not a privilege. You also don't see what happens at unload time, because you easily step off the bus and you are happily on your way. ECVs are the last to be off the bus - guests get off first, then the ECV. Once again, you easily go ahead and get to your room or the food court etc, while we are being unloaded.
Are there people who don't know how to drive and knock things off of the shelves and who are jerks? Of course! but I could show you just as many idiots who have two good feet who cause just as many issues.
It all balances out - and we all need to be patient.
Sorry for the vent - but many won't understand this until they need to go through it themselves or with a loved one.
