Cards for cars in Thunder Road!
Each player gets (either randomly or by drafting) a card for each class of car, which will indicate their respective cars' special powers.
The cards can also be turned 180 degrees to indicate damage (for using the house rule that cars can take a hit before wrecking).
Cards for extra large cars are included (tractor trailer, limo, bus, road tanker). Extra large cars take up 2 spaces and enter the board on the road on their owners' first turn. Players roll 4 movement dice instead of 3 when using them (because they will each have 4 cars).
