If you were traveling at a constant 100 mph, it would take you 249 hours to travel around the circumference of the Earth, and 2,389 hours to reach the Moon. If the distances are actually accurate then these achievements should be nigh on impossible to get in any reasonable amount of time. That now 0.2% of players have them means the distances aren’t accurate, that they used an achievement unlocker, cheated in-game, or have a fuckton of playtime.
That 0.1% is the number of players who have the achievement, not OP’s completion progress. But it’s also probably very small.
