@skinnylatte I agree up to a point, especially for shorter distances. Long journeys are far faster by tube though.
And I agree about Singapore, I naturally tend to gravitate towards metro/undergound, but in Singapore I realised there are lots of places that are actually quicker and easier to get to by bus (it probably helped that there as a bus stop right outside the place we stayed at 😁).
And Singapore buses have AC, which London ones are mosly lacking...
