I live in a very walkable part of the world with great public transportation, and still people don't seem to walk anymore. It's electric scooters and these weird electric mopets.
I was in the city the other day and walked in between some people. There was a tram arriving and most people around me started to pick up because they had to catch it. They looked like they were running, but were barely faster than me walking, and some of them were slower, because they had to catch their breath on that epick 100m sprint. I think wall-e wasn't too far off.
