I remember when Elon Musk was peddling the hyperloop idea and he was saying that we could make tunnels everywhere. At the time everyone was obsessed with cars, but perhaps it's an idea worth exploring for making bicycle travel feasible all year. Imagine a network of air conditioned tunnels across the city that people could ride in and never feel overly hot or cold.
Its not unheard of to have underground walking tunnels in cold cities connecting buildings and areas, but I haven't heard of any expanded to support biking.
University of Calgary has a bunch of them if I remember right, can get all over the place underground when its cold AF out.
As the hot days get hotter and the cold days colder, sometimes within the same day, we'll be forced to look at how we make travel viable for everyone. There will be a group that lobbies for more cars and then the sensible will look into how we can make travel viable for everyone sans cars. Pedestrian tunnels are just a possible option.
Is snows 3-4 months of the year and is regularly below freezing. I love riding my bike and did some pretty rough weather when I was younger in Boston, but I just don’t have it in me between mid November and mid April.
I don't believe you. What you're describing in regards the weather is most of Australia and it's even more car dependent then the US. If you were there, you'd drive.
It's snow bound northern Euro countries that are way more advanced in being car free then sunny warm countries. Have you seen Manila? Jakarta ?
