when i was in my teenage i used to speed alot inside the city, now when i think of it, feel real stupid of myself.
as most of the people have the habit to walk in the middle of road even when they are horned, i used to bang my left side mirror on the a** of guys ( not ladies, i respect them ), once i banged the left side mirror to a guy. when i came home i got to know that the guy was my eldest bro 
other things which i did inside the car weren't stupid
