How is that any different than today?

Sorry you lost a leg, but I think you could understand that I would maintain what I'm advocating for which would be that you using a motor vehicle for legitimate needs doesn't mean everyone should have to use one for their day-to-day needs.
While I don't have any sort of clear statistics here, if you can't walk or bike I'd imagine many also can't or shouldn't be driving. There are solutions here, including mobility services. Leaping toward "well I have a physical condition that mostly requires me to use a car therefore everyone should have to use a car for their needs as well" doesn't seem like a good solution to me.
To add, I think as we're talking about people for whom walking and biking is difficult we also forget people for whom driving is difficult or unrealistic. The elderly in particular, those with other medical conditions, etc. You might say, yes we should solve that problem too. And I agree, but what I'd say is that society right now is 100% car-first everything and does not even attempt to address the concerns of these people either. Should they just stay home too?
On a lighter note, I've heard many people who have experienced the loss of a limb do well on bikes. I hope that's something you could try and find enjoyment out of if you so choose. Best of luck there. Sincerely.
