For experienced players: If you find that some players are too slow for a racing game (fast is good), then a countdown timer might motivate them. One player should start a 2- or 3-minute timer on their cell phone (decide how fast you want your game to be) after all players have refilled their hand to 9 cards. If a player has empty registers at the end of that time, they must shuffle the cards in their hand and randomly fill their empty registers.
