Um… not to be a party pooper or anything, but everything is built the wrong way. It’s like the cars are supposed to drive on the left side instead of the right! What a shame that so much time and effort went into building a broken roundabout 😔.
It's actually just an asset I found on the workshop. Called raised roundabout, or something similar. I did need the procedural objects mod, to get t to st at the right angle.
