No problem lah having MRT to Cyberjaya. But maybe should connect further to places like Dengkil and Banting.

Think about the London tube connection. It is like a century old now, but its connectivity is like spiderweb. Can go almost anywhere around London and its surrounding.

No harm to do that. But prioritise the densely populated areas like Shah Alam, PJ, Setia Alam and maybe Bukit Jelutong and Puncak Alam. Oh don't forget Semenyih, Beranang all the way to Seremban too!

using your logic, places like Semenyih, Beranang, Dengkil, Kuala Selangor are highly populated. Building an MRT there are not waste of resources. No?
