To add to it, racing for me has always been purely fun. Just working on or building a car is something I really enjoy. Racing for pinks just goes entirely against that though with all the rivalry and grudges and the fact that you might be walking home. Of course with any racing there's competition but theres some level of sportsmanship present that keeps it fun and competitive at the same time.
Don't even get me started on the whole boy racer import street racing scene...
