People who ride or make angry gestures and expressions at a student driver car should get stones thrown at them in a public shaming. Experienced drivers always look down on the younger drivers who haven’t had practice, which makes no sense because they were once beginners. The sign is on the back and front of the car for a reason, do not ignore it. Experienced drivers are always in a hurry in big towns and that makes student drivers nervous when they try to get as close as they can to the practice car even if it risks an accident.
