they are a niusance, but in all fairness there are nice ones as well. i got rear ended smack in the centre of my rear bumper by one once. to my surprise, he did not run, or even call his 'gang' or intimidate me. he actually stopped and looked over the damage with me, and ask how did i want him to settle. he tore his jeans and the damage was cosmetic, and since he was so nice i also no heart to angry, so i asked for a sorry and sent him on his way... he restored my faith in malaysian motorcyclists.
