I have always imagined about such devices that allow you to somehow communicate to other motorists on the road (other than just the basic left/right hand signal lights of course).. and as I was surfing around today, I actually found one!!! This is exactly the thing Malaysians (especially Klang) drivers need! It's got the basic happy and sad smiley faces, displays 'Thanks', 'Back Off' and 'Idiot'... although if I were to get it, I'd customise it to display a middle finger, and change the 'Ba' of 'Back Off' to 'Fu'. Talk about instigating road rage, heh!
