>>9499762The old ones were made by a different factory than the ones Lego bricks are made in, and weren't entirely system compatible (AKA you can't build below them). The new ones fix both of those but introduce another problem in the form of the various 2x4 tiles sticking out like a sore thumb. Honestly they should've just done something with the already existing 8x16 plates and just released a pack of stickers to use for road lanes/turn markings/crosswalks/etc.
