Well,

1 Olympic Swimming pool = 50m * 25m according to wikipedia.

That means: 1250m2 per pool. Now multiply this by 1140: 1.425.000m2. Which is 1.425 km2

Especially since their models ditched the camera for “structured light” whatever it might mean.

Yeah, but for short trips this doesn’t apply. E.g. I might drive 30 minutes for a 10 minute stay/task.

No there shouldn’t be a consequence. However, most of this is related to server-load.
