Abstract
It is presumed that young non-drivers would make a decision to own a driver's license without considering negative aspects of car use. With this recognition, previous studies showed a long term effects on driver's license owing behavior of information provision of negative aspects of car use, from field-experimental studies. This study implemented field experiments where we provided negative aspects of car use such as driving costs and risks to university students in Kyoto University and Tokyo Institute of Technology, and found similar effects of such information that was shown in previous studies. It was also shown by the experiment that there was an asymmetric postulate of effectsof positive and negative aspects of car use.
