I believe that it must be the man's DNA that trying to proof to his GF that how MAN he could be!!
Ha..Ha. If that is how men are supposed to proof their manhood in Taiwan, I guess half of the male populations might not exist at all. Funny though, no matter where you live, you get to meet these kind of so called"retard" on the road. When I was younger I would simply over take his car and see what his has got" Let your car doing the talking" but now my own perspective is "he can shout his lungs out but it will still not change the fact that you still have a better car!!!! That kind of makes my day hopefully it will help you in the future but fingers cross that you wont be meeting those people again.
