>Not every person is able-bodied enough to walk and bike
And the same goes for cars, except kids can ride bikes, so car accessibility is actually just worse.
>Also, people happen to need to get from A to B when it is cold, dark, raining, extremely hot, snowing, or just some kind of shitty outside
You can walk or cycle in all of those conditions. In fact, I have walked or cycled in all of those conditions in the past 6 months.
>People need to drive to a store for food or supplies that cannot be carried or biked back to the destination
There's very little that can't be carried on a bike or public transport, but you can always rent a car for a couple hours if needed. Let's be real, that's not why 99.9% of people are driving cars.
>People have multiple children that simply cannot walk or bike
Where I live it's common to see mothers cycle with their kids on child seats in their bikes.
>Old people cannot simply walk or bike.
And a lot of them can't drive either.
