It's not in the interests of the UAE to improve. There's the (possibly misattributed? but topical nonetheless) quote by the previous emir of Dubai:

> My grandfather rode a camel, my father rode a camel, I drive a Mercedes, my son drives a Land Rover, his son will drive a Land Rover, but his son will ride a camel.

They want to prolong the Land Rover phase as long as possible.
