Bus & Stop: My Favorite Mechanism

About Bus & Stop, from BoardGameGeek:

Bus & Stop is a card game in which you compete as bus drivers to bring passengers to their desired destinations, while avoiding overcrowding. On a turn, you either pick up or drop off. To pick up, choose all of the passenger cards of one color from the row waiting at the bus stop, then place them in your bus - that is, the area in front of you, which can hold at most ten cards. Senior citizens aren't going far, so you score them immediately instead of placing them on the bus. To drop off, choose a group of passengers on your bus that match one of the available destination cards - for example, all men, all girls, or one passenger of each color - then remove these passengers from your bus and place them under the card. You score points for each card depending on how many people you delivered at once, so aim for large groups. Whenever a player drops off, everyone else can make one of their matching passengers skedaddle, removing them from the bus and placing them in a personal scoring pile with their senior citizens. When the bus stop can't be refilled with passengers or only a certain number of destination cards remain, the game ends. Tally your score, earning 1 point for each single card and the listed points for each destination card. If your bus is empty, congratulations! You earn a depot bonus for not stranding passengers on your bus. They will thank you for not doing that...
