And where I live it's 110F+ for three months of the year. No one sane is biking or walking anywhere as it's too dangerous. Not everyone lives in some temperate small European city.
Second,I live in Tokyo, where the summer has been miserable with average temperatures of 32C, with regular highs of 36+ with 80% humidity. And yet I walked and biked everywhere and was just fine, and that's true for most of the 40M people that live here as well.
Third, it sounds like you live in a place that's not suitable for humans, you should probably move instead of making the planet even hotter for everyone else by living in your steel boxes with AC.
And this is where you need to remember that the rest of the world is not Tokyo. I have faith you’ll get there.
I dunno about 3 months exactly, but some areas of India are pretty close. And Delhi has 15-30 million people, depending on how you count
And would you mind not being a condescending prick? If you had taken a second to google you would know Tokyo had highs of 40+ this summer.
Sounds like you're just trying to make excuses for your awful city.
