So, using the front side, this just adds two spaces to the track, and on the back side, it works like an uphill, but only with one lane, meaning people can get stuck behind? Weird that it didn’t come with any rules.
Aren't the rules built into the tile? It's a 2-space ascent: max 5, no slipstream, a single lane space.
Kind of a missed opportunity IMO since the tile is 2 spaces, which we already have (yes, they're turns, not straight, but that doesn't matter). I think 2 single-space tiles would have been a lot more useful, and make them ascent one side, descent the other side.
