Sonic's Speed Highway - Sonic Adventure Autodemo

Sonic's Speed Highway in the SA1 Autodemo. Sonic's Speed Highway is used in his demo and is one of the more stable levels in the game. Act 3 is totally different to the one in the final, though you can't access it through Act 2 due to a blocked wall and cheating to go through that wall gves the level incorrect textures, so it has to be accessed from the level select menu. Also there's a big chunk of a building missing in Tails' part and I find that funny.
