Also, I would add that subways are probably a better way forward than busses for a modern city, or at least some sort of connected underground transport system.

I also agree that Subways are awesome - and Singapore has an awesome system for such a young country, and they are going to be adding a new one each year through 2024 - That's a new line, not just a new station. [1]
The nice thing about bus stops - is they are everywhere, and the buses come by very frequently, and they all have GPS locators on them - so you can time your arrival to the stop to be when the bus arrives (which you can look up on your smart phone). I've never been a fan of buses before Singapore - but it's great to see what can be done in a country where cars are not the default option.

I rarely bother to even use their (world class) MRT I love the buses so much.
An advanced city is not a place where the poor move about in cars, rather itβs where even the rich use public transportation
