As a frequent traveller, I would be much more inclined to either pick the airports that are going to be relevant to me ever or pick the destination airport when I am at the source airport which Uber can easily detect. I am visiting ~10-15 airports most of the time. I would be happy to spend some time to set this up on my phone so i not need to waste a huge amount of space and bandwidth every time that I update Uber. For Uber it would be a win too, reducing the size of the app significantly. Maybe it is only me.

A willingness to put in some time up front to tailor a technology experience to yourself is one thing that separates the average HN user from the population at large.

For a significant majority of users, if it doesn't work well out of the gate, it's broken.

Even as an avid Hacker News user, I wouldn't tailor an app download to save bandwidth/space. Both of those are abundant.

Don’t app updates only push deltas anyway? It’s only the initial install that’s large.
