I’m often accused of being too aggressive a driver (“people like you cause road rage!”), and admittedly, I do use driving as anger management every now and then. Although I’m usually a nice calm person, piss me off while I’m driving and I have no problem rolling down my window and having a cow (hi zooks).
Isn’t this awesome? Driv-emocion gives drivers the ability to express themselves traffically without getting too extreme. Your standard :) and :( are options while text such as “back off” and “thanks” offer a more direct expression. I’m not sure it’s expressive enough for me, but I love it anyway.
