I am so glad you liked it!
Eventually falling off the road would trigger spawning on the central island with unloading all your stock to it and 1 day passed, but the trigger zone somehow resetted to a very low point (you will hit it. eventually). Resetting was supposed to turn your truck if it has fallen on the roof (first iterations would do this on every slope), but we somehow fixed it and it remained kinda misleading.
But, you can use it to hack falling - every reset set the truck 1m higher, so... reset-reset-reset-reset + going forward the track :D
In lore version of the game that fell out of scope you would drive with robot assistant, who would help you not to fall off the track, but we set too much for the time we could spent :')
