Rats trained to drive tiny cars show excitement for the activity itself, study finds

Scientists at the University of Richmond have found that rats trained to drive tiny cars show excitement for the activity itself, not just for food rewards. During the pandemic, the rats eagerly approached their cars, indicating a strong motivation to drive. The researchers observed that the rats often jumped into their cars and revved the engines before driving. This behavior suggested that the anticipation of driving was as rewarding as receiving treats like Froot Loops. In experiments, when given a choice, most rats preferred the longer driving route to a reward over a shorter walk. This led scientists to conclude that the rats enjoy both the journey and the destination.
