Remove Tires/Clean Trash/Inflate Balloons/Roadblocks

Tires, trash, and balloons are very similar objectives. There can be only one type of the objective on the board (e.g. you must remove 3 tires, so there are no balloons or trash). To score the objective, you need to match cars on tiles adjacent to it. Trash requires one match, tires two, and balloons three.
