The first observation is how awful the air quality is. Holy cow. This report from Plume Labs (snapshot from the time when I took this above photo of the skyline) tells the story:
While the air quality has made it a bit difficult to get around (no views, but more importantly, you just start to feel sick after a while), something else here has made it tremendously easy to get around: the Octopus Card.
The Octopus Card is a reusable, contactless smart card used for payments throughout Hong Kong, which most importantly works for nearly all modes of transportation. Yesterday, I traveled by high-speed train, subway, streetcar, bus, tram and ferry, and used my Octopus Card to pay every time (it also works in some, but not all, taxis).
It is hard to overstate how much of a convenience this is, especially to a visitor to a foreign city. I traveled by seven different modes of public transportation yesterday, and had zero cognitive overhead trying to figure out tickets, rates, etc. It is really liberating and makes exploring a new city so easy and so much fun.
Similar systems exist in other cities (Oyster Card in London, UPass in Seoul). It really makes the city so much more accessible, both for residents and for tourists.
Experiencing infrastructure like this makes me realize how broken and unusable most of the US equivalents are. Imagine if you could pay for a train, subway, bike, and ferry in NYC using one system? It is a shame we can’t make investments like that work (by and large) — the closest is perhaps EZPass, which in the American tradition works for cars.
