@HellloBambinos and I don't disagree with the need for cities to have less pollution and better public transport options on the whole. I would love to be able to get suitable public transport, and get safely to my inner city hospital appointments and not pay for £20 of parking that it costs me to see my specialist. There needs be significant investment into suitable infrastructure, cycle lanes, public transport accessible for a variety of disabilities, not just with a ramp and a few folding seats fitted as an after thought that someone who is able bodied thinks is accessible, lots of seating at varying so that people with disabilities can sit often whilst walking, longer time on pedestrian crossings, the list goes on.
My worry however, is that people with disabilities are often marginalised and forced to "prove" their worthiness for almost every single provision that they have much like your "regulation" idea. There are entire businesses built on the premise that people with disabilities are inherent liars out to defraud or gain special treatment. We don't need any more hoops to jump through, more things to have to qualify for to be able to continue to participate in life.
With the right incentives, one would hope that people will choose to make better, more ethical choices of their own volition without making it an "us" and "them".
