It's on the letters the council keep sending me warning me that it's a legal requirement to register and I could be fined £80 if I don't. (I am registered, at a different address).
RTS games are fairly unique in that you always know you could be doing things slightly faster, constantly. Yes, you can make a big mistake that loses you the game (like losing a queen badly in chess), but often if you just did your macro tasks a little faster you would have won, or scouted every 30 seconds instead of 35. The article touches on this in respect to APM.
We have a related problem in the UK. Sometimes very small "country lanes" have no explicit speed limit, so defaults to national speed limit of 60mph, which you would have to be suicidal to drive at (or just hate your car), but Google maps still often route finds along these roads.
This. Google has a major advantage in that they have a massive dataset. They can use their data to improve the cost function even in real time to detect traffic.
