Yeah, it’s clear you’ve never lived in Singapore. Lots of important places are inadequately served by transit including major universities, many major embassies, important employers, the best food centers, and many of the popular Western expat neighborhoods. Want a bit of nature? Hope you like a 30 minute cab ride to the Pulau Ubin ferry terminal, which is also not served by transit. Want to go out for drinks? MRT and most buses stop at midnight. Maybe it’s only a 10 minute inexpensive cab ride home for you but your Singaporean friend probably lives in an HDB in a more remote area and is going to have to go a lot farther and pay a lot more.
Oh yeah and even if transit seems like it’s in close proximity, many of these areas are seemingly designed in the most pedestrian hostile way possible. What looks like a 10 minute walk can easily be 20 minutes once you factor in absurdly long pedestrian signal times and having to go over overpasses etc. And the average temperature is 30-32 degrees, it feels like 35 when humidity is factored in.
Easy for you to say “take Uber” but Uber left SG last year, it’s now Grab which is a much worse experience. And good luck getting a Grab or a taxi during anything approaching peak hours, or when it’s raining. Do you commute by cab every day where you live?
