Yeah apologies about that, this was created a few years ago when CSL was still an infant, and I didn't realise that prefabs are best created in RHD and then let the user decide with the Left Hand Drive checkbox... I planned on updating all these but time and life got in the way. You can use the Upgrade road tool and right click and hold and paint along the roads and it will invert their direction, sloppy workaround but it's doable.

Too bad there's no right hand version :(
