That's where the rest of us come in. I for one would much sooner take a grocery delivery job if it's a critical service for the elderly and disabled rather than midnight pizzas for potheads.

The idea that a car is the only lifeline for people with physical disabilities bespeaks broader social ills.

Mobility scooters are not only for the morbidly obese.

Electric scooters (with seats if need be) are good enough. Moving a ton of metal for errands in city is insane.

What if you live in US but your health doesn't allow you to drive a car?

That is where exceptions come into play. Yes people with disabilities (which could include elderly people) will need a different form of transportation.

But exceptions to allow those that need it to drive or other services (like grocery delivery) can take care of that while still allowing for a pedestrian focused city.

There is also the fact that if a city is properly designed ideally you may only need to walk a couple blocks for groceries and your basic needs, and instead of doing big shopping you buy just a few things at a time.

Golf carts?

Try driving to get your groceries with epilepsy or a vision impairment.

If you're physically unfit for an electric tricycle (or even a scooter without pedals...), I kinda don't want you drive a 2t+ vehicle at 50km/h or more.
