Sprites have wiper assemblies which are quite crude. The one-speed motors wipe slowly at best, and if you think you’ll drive in the rain, you’ll do better with Rain-X or a similar coating on your screen. Wipers help, but not much, even under the best of circumstances. Fortunately, these are largely fair weather cars, so the wipers are seldom used. You do want to make sure your wipers don’t do any damage to your car, however, so it’s important to be familiar with the system.
