^^ Lack of air conditioning in buses is an odd thing, I certainly agree. Only a handful of them have it here in Frankfurt and we damn well need it. Though I know the German reason. They are all a bunch of hippies here and think AC is both bad for you and the environment.

Stuff that when it's hot.

But honestly, what is so much better about HK and Singapore's rail infrastructure besides both being so new (which means for a long time they had no subway system and thus really bad public transport). Yes, it's cheaper as well, but both Singapore are tiny island nations with incredibly dense populations - this does make public transport (and infrastructure) unbelievably cheap in comparison. Both are quite limited in their coverage, though I do agree they seem to cover a good area for tourists.
