Same for me. It's simply the convenience. I can get an Uber driver to pick me up from anywhere, even a street corner, even without knowing where I actually am, other than phone GPS, within a few minutes. Last time I called a taxi, I had to walk half a mile to a location I could describe (nearest restaurant), ask them for a taxi service I could call that would pick me up there, called. Was told I had to wait an hour. Waited an hour, and called again, and they said they didn't know I was waiting and had to wait another hour. Driver finally picked me up in a barely running mini-van, and was surly that my destination was far away from his normal routes. Outside of New York City, I've used Uber exclusively since.

I would invite you to do a quick google image search for "Cell coverage in canada" and "cell coverage in australia" and "cell coverage in the united states". Do the same for "population density". Canada's north is mostly empty. Australia's interior is the same. The US has people basically everywhere except a few small locations because most of the US is habitable land. Per-capita they may be less dense than the US, but their actual populations tend to be clustered making the statistics misleading. The US has a lot more people that are spread out a lot more. The US really is harder to provide land-based infrastructure for people in these rural areas, but at least for cell coverage, they are arguably doing better for providing access in rural areas than either of your examples.

At least in my area, this is available. http://chart.maryland.gov/map/ Allows you look at all the traffic cameras live. I do not agree however, that all data should be public. For example, the government has access to people's fingerprints. Allowing public access to that data would make it quite easy to frame whoever you wanted for a crime.

Water can take away a lot of heat fast. It's heavy and bulky but it can be stored in skin tanks on the wings so it ready to go when needed. Under pressure it would flow out any hole made by the laser and remove the heat quite fast.

If water is "heavy and bulky" and needs a pressure container, which is also heavy and bulky, I question how useful of a defense system this is on what is supposed to be a light-weight fast-moving flying object.

MERGE is absolutely atomic. It either entirely fails or entirely succeeds.

That's not what atomicity means.

Actually it's exactly what atomicity means in this context of a database transaction. In an atomic transaction, a series of database operations either all occur, or nothing occurs. You may be confusing it with an 'atomic operation' in programming. https://en.wikipedia.org/wiki/...
