I'm amazed nobody has made this, as many other things similar have been made. I'm wondering if anyone could make a pack of road ramps that fits with the default road bricks. I guess they would be 25 degree, 18 degree, 10 degree, 25 degree curved, 18 curved, 10 curved. This would be very useful for people who don't want to change every road in their huge ass map when they need a change in elevation that doesn't make cars get stuck from bouncing around a ton.
