Habibi, come to the UAE or Qatar
I guess I see the unfinished projects as being the proof: The World and the 2nd Palm haven’t been finished because they (I assume) stopped making commercial sense to the developers.
I would finally note that Dubai specifically has little oil and gas wealth. Maybe 1% directly and 10% that comes as subsidy from AD which has plenty. The rest is literally just a combination of smart and commercially savvy governance combined with an essentially unlimited amount of desert to build in.
Once I had an issue with bus routes for my father's employees (similar problem, high density route with fewer routes). I put a request on their dashboard from abroad and within days, their reply came back with them confirming a trio of new buses to cater to that route.
Another time, I had an idea for bus route planning (not related to above, that relied on a simple ping system for bus driver notification). I sent an email describing the idea in short to the Emirati CEO of the bus authority, and within 15 minutes, he acknowledged my email and connected me with his advisor to set up a meeting the next day. The advisor (an Indian with a US PhD in urban transport systems) discussed my idea through over a meeting.
Oh, and there are self-driving bus demos currently happening in Abu Dhabi right now.
Well, that's what happens if you can just throw money at problems. In Germany, it would most likely get rejected because there are no spare buses/drivers or budget for the fuel, and even if there was money it would likely be delayed for at least one year because the new route would have to pass through the usual tender/bid system first.
And in terms of overall development strategy, its very often very Americanized. Big highways, big highway interchanges. Dubai is known for basically building everything along a very big highway. There is no reason for a country this small to ever have a highway this large.
Given how trivially easy they are geographically their modal share in public transport is not very high at all.
Does feel like the Singaporean economic miracle is under a lot of pressure. Demographics and retirement savings I guess being a big part of it.
And slaves.
Lots and lots of modern day slaves.
