If only we had invented and built some sort of alternative mode of collective transportation. Maybe it could be in tunnels and ride on metallic rails. It would serve many people and make periodic stops to the same locations instead of the highway clusterf- we have today. Sad that we don't, but a man can dream though. A man can dream though. A man can dream.

maybe americans shouldn't build their homes 7km away from the nearest grocery store lol. jokes aside revamping us infrastructure would cost too much.

how does this community look at "the line" being build in Dubai. u can have all kind of opinions about dubai, but the line seems like the easiest solution for public transport. one train/bus/metro line goes up, the other down lol.

    The Line is very stupid.

    At 200 meters across and 170 km long it has a surface area of 34 square kilometers.

    Let's assume that instead of building a giant line, we build a bunch of highrises next to each other with the same height and same combined building footprint (so, same internal area). To account for the fact that we would need streets between the buildings we'll just double the required area to 68 sq km (the line's design already has internal streets, so this is a high ball estimate).

    The resulting city, if it were a circle, would have a diameter of 9.3 km. Which means it would take you about 23 minutes to get from one edge to the other (worst case trip) by riding a bike, or ~12 minutes to get from the center to the edge.

    As you can see stretching a city out into a giant ribbon makes things very far away from each other for little benefit. Water pipes are lines too, and while building your city like that would mean that you'd only need one big pipe it certainly wouldn't make it easier to distribute water if you had to pump it a hundred km.
