All Stadium Free-Wheeling Blocks without addictional signs on the sides.

There's a way to access the old freewheel blocks that are still part of the game data (for backwards compatibility with older maps).

The difference between these and the newer freewheel blocks is that the new blocks have signs on each side of the block, partially blocking the road.

NOTE: If you open your map in the editor with those blocks, unnecessary signs might appear back on freewheeling blocks.
