I've been thinking there should be a "sticky" or "traction" blocks similar to the coasting(?) blocks in look, but work differently by making the car stay on the track even when going up at high speeds. To make sure nothing weird happens if a player goes on a wallride or off a ram...

Not a super huge expectation/want, but I think if a few peices that look similar to/exactly like peices from TM2/TMU were avaliable for use in editing would be kind of cool. Not the track peices, but some of the other things like buildings. It's kind of cool finding that in games.
