One of the reasons why dogs like to chase cars is due to the prey drive and the success they feel. They run after a car, barking and the car keeps going. in the dog’s mind, it thinks it chased it away, so it reinforces that behavior. This is the reason why you see people enjoying simple tasks such as burning rubbish. They light the fire, the fire burns, the rubbish is good, success. We tend to do things we achieve success at, same as dogs.
