What do you wish could change in our society to improve your life quality? Ie better designed disabled toilets, automatic doors everywhere etc etc. @Vallmo47 thank you for this question.
Infrastructure
Ramps, ramps, and more ramps. Seriously, the number of shops and restaurants, opticians, banks, even doctors, that have a step(s) to get in and no ramp available. Ideally, as many places as possible would have level/ ramped access built in, so as not to have to ask to get in, but if that's not possible, at least have a portable ramp.
Doors are less of an issue for me personally as I only use one hand to drive and have full use of the other arm, but I know automatic doors are essential for a lot of wheelchair users, so yes.
Disabled toilets that aren't used as storage for cleaning supplies, have proper red cords all the way to the ground (safety requirement), have proper space around the loo to transfer (again not an issue for me personally). Baby change tables in the disabled loo should be low enough for a wheelchair using parent to use, if they're too high for us to reach properly, put them somewhere else. One in the mens, one in the womens, perhaps. And if it must be at standing height and in the disabled toilet, it should be a flip up one, not a fixed table, as that takes up way too much space in the average disabled bathroom. We need room to manouever.
Seatbelts in the wheelchair space in buses. In Spain, there is a seatbelt that can go around the back of the wheelchair to secure you in place, as well as a bar. With a lightweight chair, that is much safer than just the pull down bar on UK buses. Otherwise I end up clinging to the rail for dear life and putting my shoulder out. Also, two wheelchair spaces instead of one wheelchair space and an awkward flip down seats area that would be big enough for a wheelchair, they just haven't put in the backing and the bar. Again, something on Spanish buses. Usually just avoids conflicts with buggies, but occasionally both are needed, plus I could actually travel with a friend who also uses a wheelchair.
Speaking of buses, a better public transport system, cheaper and more frequent. When you might not get on a bus because the one space is occupied, having buses every ten minutes would be vastly preferable to a bus every 30 minutes or an hour.
Attitudes
Disability civil rights history should be taught in schools, along with the basics of don't touch mobility aids without permission, don't ask intrusive questions to strangers going about daily life etc. Most people don't realise that our predecessors fought for us to have access to public spaces, and that we are still fighting every day.
I would like people to realise that getting disability benefits (PIP) is a long-winded, intrusive, and often traumatic process, for very little money.
And I would like for people to know that just because someone can move their legs, it doesn't mean they're "faking it" or don't need a wheelchair.
