I agree with your point as a disabled person - and here in the UK we kinda have this system. My car is registered disabled and therefore I can drive into LEZ, ULEZ and CC areas for free automatically. It’s a literal life saver when I survive off benefits, physically cannot use public transport, but I’m treated at hospitals in the very centre of London.

But the term “handicapped” is outdated and is considered offensive by some. Perhaps stick to “disabled people” instead.
