Beta Mario Highway (3) - mr_highway_demo (Model) - Mario Kart Arcade GP 1/2

Filename is MR_highway_DEMO_A.dat
I believe this to be a third beta of this track. Based on the name, this collision (not seen here) and the model may have been used in GP 1's attract mode.
I viewed it with Smash Forge, which supports some of the models in this game. For some reason I couldn't get some of them to work, but this one does.
This is yet another beta remnant leftover from GP 1, because GP 2 was built upon that game.
