To Americans: How far apart is everything in the US? - Lemmy.zip

I’ve heard the legends of having to drive to literally everywhere (e.g. drive thru banks), but I have no clue how far apart things are. I live in suburban London where you can get to a big supermarket in 10 minutes of walking, a train station in 20 minutes and convenience stores are everywhere. You can get anywhere with bus and train in a few hours. Can someone help a clueless British lemmyposter know how far things are in the US?
