I've chosen 60304 as my one a month ,I don't have a layout and only own 2old style road plates(straight and bend sections) these are more robust but need 2plate height for a street, 6wide just pass ,8wide must give way. A mod would be add 1stud width either side ,limited furnishings and the extras -flower plant stem and 2flower heads, and 3 1x1 trans round plate . The street lights aren't very high so trailers beware! I put the luminous pieces up to a light to charge them ,obviously not illuminating but having a lit effect on a fairly dark room, maybe with a set every 150mm and you get down to street level they might be more impressive.I hated the floppyness of the old plates but these are extra work and I don't know how they'll create a curve.there's on/off ramps and speed bumps too but my lowrider rig wasn't a fan .I've dipped my feet but I hope I can find an old style road plate supplier cos I'd rather not take this route
