The whole point is if we prioritize transport other than cars, we don't have to sit for hours in 90 degree heat. We walk, take the bus/subway, or bike, scooter, etc.
This doesn't even require everybody to live in a city... I'm outside DC and just moment from my front door, I see plenty of opportunities to make transit better and reduce car usage... I'm 1.5 miles from a subway station, but it's impossible to walk to without crossing 1 or more 6 lane roads. There are bike lanes that lead nowhere (literally end a few blocks before the local school then start a few blocks after, then stop before the local shopping center, then start again after). They just built an expensive bike path/running trail as part of an interstate project but they put it right beside the highway - who wants to walk/run/bike 4' from trucks belching diesel fumes and with dangerous sound levels? They could have built the bike path on the other side of the sound wall, but didn't.
