I got one ... i usually want to see whether a 'chiong car' got
power or not i tail then with my low lights on then very near them
then blast high beam ... they will get pissed off and think you
want to jio them ... after that they full blast!
After you see the acceleration of the certian car, it will helps
you greatly if you are looking for a car but no chance to see its
performance 
(now you know why i got a sunny)
