They may also experience some anger or resentment for being challenged and by taking part in the race, they may release some of the negative feelings that result. Methods of Interaction One of the most common methods of interaction when overtaking someone is signalling with a left or right blinker. In the cases that I observed, a large number of the drivers who overtook another car signalled with their blinkers each and every time they attempted to overtake a car. Most of the cars that were being overtaken responded by decreasing or maintaining their speed. The methods that I observed occurred in the Big Island, and although it is difficult to generalize my results, it is safe to say that to some degree these methods may be found in almost all driving environments.
Most people use the different methods of interaction for overtaking.
There are a select few people who do not overtake cars. The 3 males in my study all overtook at least one car during the time that I watched them, and both women I rode with did not overtake any cars. The methods of interaction that I witnessed during my brief study were very effective. Because all of the drivers understood what was about to take place and agreed upon this occurence, the smooth-flowing nature of the traffic was preserved and the dynamics were kept intact. The gesture that I saw the most when one car was overtaking another was the waving of a hand.
