Racing Sims rely on Online Data to a certain extent, although not “streaming” that is neither here nor there when it comes to a basic Beta Testing program, MMORPGS utilise “Live” severs and have had far better Beta Programs in the past (Elite Dangerous for example) so again it’s not like Asobo/Microsoft wouldn’t of known about them, begs the question why leave it so late to start one when it’s so blatantly obvious that a Game/Sim of this magnitude neds one from the very beginning.
As for the Horizon Line bug:
and the POIs LOD issues, which this thread shows Asobo exactly how to fix their problem, simply fly to the White Cliffs of Dover/Devils Tower and you’ll see what the issue is:

The Tree LOD has been dramatically altered and is an issue, like above perfect examples of things that are broken then left to rot for months until a fix eventually comes along. IMO when a new Bug surfaces via a Patch then that Bug should be prioritised very highly, not left for ages with little to no sign of being fixed - hence my dislike at the Bug management part of the Sim, amongst other areas!
