Biking, buses, trains, underground tunnels.
I sometimes have biked to work in the summer not far from where that picture was taken and I live like 15 miles away. Its even more comfortable if you use an ebike. Unfortunately, I get that’s not an option for everyone (personally have been off the bike due to an injury this summer).
Not everyone is a masochist. A lot of people find Houston heat intolerable.
So lets cover it in only asphalt that absorbs that heat and continuously vomits it back up over the course of the entire night. All this shit is self defeating, and a major cause of the situation we find ourselves in. Car infrastructure also encourages longer distances between destinations. Roads eat up more space than alternatives, and cars themselves are large vehicles. This, along with the increasing speeds of cars encourages society to spread out. Without it our cities would be more human-centric.
I hate the heat too. I much prefer it under 60 to over 70. But when you’re moving at a good pace and you don’t have to travel 15 miles because of miles of space wasted by cars, its not bad. Also, buses/trains should have AC. If you have a well-designed bus system, you aren’t waiting for buses much, if at all.
