We wish they were that cool, the inventors of the modern mile were more concerned about land measurements. A square mile is 640 acres. Which neatly can be cut into quarters 3 times. 160, 40, 10.

I don’t know why we should be surprised. This is just natural progression and even if they don’t explicitly send it out to a specific location on its own eventually it will find and consume the information in one way or another unless it is kept in an isolated box. There is absolutely no legislation that will fix/stop this unless 100% of all people capable of creating these will respect such a decision and being the odd groups out will severely hamper their future.
