> I was actually worried my point may come across like this and considered clarifying,
No, I understood, I was trying to tell you that roads are, and were, for travel and that's it. This public space you love never occurred on roads. People have ZERO interest in doing anything on a road except getting to their destination. We have lost nothing whatsoever.
> vehicle traffic existed alongside people strolling and standing and doing whatever the hell else
You can not bring back the halcyon days when people strolled slowly and were not in a rush. Those days are gone and are not coming back. People want to get where they are going without any time waste.
You propose replacing roads with underground subway or monorail, which are entirely unsuitable for 90% of cities. Plus they don't solve the last mile problem, I've actually never heard of any solution for it except self driving cars that don't exist, or expensive taxis. And even then you still need your hated roads!
> As I said before, the only thing I was alluding to was the fact that they were space that you could actually use, spend time on, play on, etc,
No ever actually did that. Your dream world simply never existed.
Go watch that video you posted and tell me how many people you see talking to other people. I spotted exactly ZERO. People were shopping, or going places, sometimes together. But none were using this "public space" you imagine for anything except travel.
Perhaps you are thinking of central markets like a souq? But that's only a tiny portion of the road network.
> which shows exactly what I mean about roads essentially being extensions of the way sidewalks are today (+ vehicle traffic), as opposed to the "all vehicles except for crosswalks" style we have today.
And you'll still have your hated roads even in your scenario! Only instead of carts you'll have slow autos? So in essence you want to drop the speed limit? And that's about it? So why all the text about how much space roads are taking?
Or do you want to get rid of roads to bring back an ideal that never existed and that no one even wants (periodic mini-parks would provide all the advantages and none of the drawbacks), and have no suggestions for what to replace it with?
