Over here in most towns it is available for 30€cent per Liter. But why should I schlepp around 5L containers (there is life without cars) if I can have water from the tap? Using destilled water for the final rinse is something different, but one could reduce the volume easily.
I'm at the grocery store anyway. And the closest grocery store is still over a mile and a half away, along a major road with 50+ mph traffic and no sidewalk, and no public transportation.
It's very different over here surviving without a car. It's possible, barely, in major cities. Only a very few major cities (NYC, I think maybe Chicago) have sufficient public transportation, and sufficiently awful traffic, to make it both easily workable and preferable for a lot of people.
I have two cars and a motorcycle. The second car is a bit of indulgence but it's a small wagon with high miles on it and not worth much so I kept it as a "backup" and for the cargo moving ability of the small wagon when I bought my other one.
People I know who cannot drive due to handicap tend to move into big cities. You literally cannot survive most places in the US without driving or relying on someone who does.
