Well....if you know where the roads are rendered then you know where to put the waypoints, don't you. Note that vehicle waypoints already "snap" to roads, why couldn't they snap to where the roads are/will be rendered?

because you need only one way point for vehicle to turn ( on present maps) ... if you'd have rounded curves every vehicle would need several waypoints just to make a turn ( game generates waypoints as vehicle snaps to road ).... big FPS ( CPU) killer
