I'm in Aus. Until about 2 years ago we lived on the 10th floor of an apartment block, dude diagonally opposite us had lost use of his legs. He had a wheelchair that "docked", into an electric mobility wheel thing that had a handebar with controls, battery driven. He'd use the wheel chair by itself to get around the complex, down the elevator to the indoor heated pool, had a electric lift he could use to lift himself from the chair into the seat then swing out into the pool and lower himself , float between his legs and do some laps. as wll as just get around the complex (5 towers, 13 floors on each) Then he could dock it into the electric front wheel thing and head across the road to the shopping centre to do groceries etc. Turned his manual wheel chair into a three wheel electric trike Not sure how far it could get him, I never asked but was also much faster then walking speed to get around.

I don't think anyone wants 100% car free but an 80% reduction should be an attainable goal eg electric taxi to take you places and a better chair!

Stay sane !
