Yep, thats what this is

Yeah, I dunno why OP put quotes on it.

My guess is OP is being sarcastic because progress to many people means more highways & cars. More construction and development.

I wish we had more of this kind of progress near me (Colorado USA).

The road and cars still exist, they just put it underground

So, as a not very smart man. Wouldn’t underground roads be better? I feel with it being underground it’d be easier to manage pollution and install some things to fight it.

Underground roads are crazy expensive. You need something to hold up the earth and anything else above it. There’s issues with water leaking in. Piping will have to go around it. If it breaks down somehow it will take longer to repair. It’s only really an option if the detour would be a lot longer or within urban areas for the extra space it frees up.

Or if you know, having greener spaces and roads underground are actually better for climate change. I’m not sure if this would help in that matter or not, but I think it’s a possibility. Not everything is about our made up concept of money.
