Why is it that these can only seemingly be found on foot?

If I land and scan and it’s 600m north, say. Can’t be bothered to walk so get in my ship and fly roughly 1000m north. Land and scan again. Now I’m 2000m away in a completely different direction. Same if I get in my exocraft.

I might be imagining it but it feels like as soon as I get in a vehicle, it moves. Also with delivery missions it’s a trade outpost I’m looking for but the ship based scan, which otherwise will detect them, doesn’t. And if I land and scan for trade outpost with an exocraft, it finds another one further away.

In short I still find this mechanic incredibly infuriating and just abandoned a delivery mission as I really couldn’t be arsed with this tedium. We can teleport anywhere in the galaxy but haven’t got the tech to narrow down the location of something on a planet any better than a 17th century sailor with a compass and sextant. Yeah this is a whinge and I know some people like it but to me it only detracts from the enjoyment of this game. We have creative mode for those who don’t like grinding, I feel like there should be an option for this also. Or just get rid of it.
