Yes if you calculate the raw distance

The reason why ppl still feel CJ is far is because between the travel between CJ and KL there is no other worthy place to go

If you stay in Klang, the travel to KL means you go through Shah Alam, Subang and PJ

If you stay in Rawang travelling to KL, you will see Sg Buloh and Damansara areas

If you stay in Semenyih travelling to KL, you will see Kajang and then Cheras

If you stay in Cyberjaya travelling to KL? You will see nothing in between .. maybe Bukit Jalil when you near KL but before that nothing ..

Thats why ppl still feel Cyberjaya is “far”
The only neighbouring city nearby is Putrajaya and Dengkil .. which is a similar dead city
