(me at the truck dealership) So how fast will this DAF go?
(salesperson, slapping the truck) This baby does 600+ kph!

The game.log.txt* - attached
The game.crash.txt* (In the event of a game crash.) - no crash, strangely.
Map co-ordinates.** (If the bug report pertains to the map or map asset include the co-ordinates.) - lemme know how can I easily get this on a Steam Deck. Or how to activate this so it permanently shows up in screenshots. But it's happening near the TS Atlas depot entrance in Gijón, Spain.
A screenshot with the mini map. - linked below.
Description of bug. - decided to try out the realism of the train tracks near the TS Atlas depot entrance. Turns out the steel beams are only visually there, as the truck's tires don't seem to go over them, but through them. Got more than expected, as the truck went straight through the ground and into the below "sea" solid layer. Effectively driving on water. Drove around some, then hit the end of the water. Except it's not an end, but a means to go/fly/fall straight to the center of the planet, hehe. Too bad SteamOS hasn't a way to record video, it was FUN. Moreover, resuming the game after exiting from free fall brings me back to freefall! MORE FUN! Got back with emergency assistance, they seem to have coverage deep below ground.
Version of game. - 1.46.0.40s
PC operating system & whether it's 32bit or 64bit. - SteamOS 3.3.2, 64-bit, running under Proton Experimental (bleeding edge beta chosen) compatibility. Eye candy.
Reproducibility of the bug. (Always, sometimes, or random.) - always

Sinkhole looks fixed now, thanks to the team!

Train track steel beams also have a feel now in that exact area, and a slightly different nice rusty color, although for the remaining parts of the tracks, they're still there only visually. But it's just me nitpicking.
