On the topic of the garbage truck, BeamNG did previously make a garbage truck for a training simulator for Waste Management https://beamng.tech/references/beamng-sigma-integrale-waste-management/
That was all the back in 2021 though, I feel like we would have gotten it by now if they were going to add one
After looking at the images I am 90% sure its in BeamNG. The only thing I am suspicious about is that it was a while ago, though this could be because they had to rebuild it to be lore freindly. --- Post updated --- They need time to make it lore freindly, meaning they likly had to redo it from the ground up. --- Post updated --- I am pretty sure that all those complex mechanisms are the trash compacter (Going with my garbage truck theory)
