As strange as this sounds, I feel that it is certainly something to be taken into consideration. I think that radio stations deliberately put on annoying adverts so that drivers get road rage and have vehicle accidents. Think about it, you start the car and what do you hear? Either the infernal racket of some presenter with a speech impediment or a company trying to promote itself with teeth-grinding advertisements. That just doesn't make sense! Unless, of course, they want you to become so enraged that you crash cars with another angered driver. What do ya think?

it worked on me, it makes me so mad GRRRRRRRRRRRRR

~thinks of modern technology~
They don't have cassette players, or CD players in the cars where you are??

But it is an interesting theory..

I went out for a smoke.. and while out there i heard the sublime echo of(my opinion) shite music blasting from a car driving down the road..
I think the real consipracy would be the stereo makers.. It is from the stereo systems that we hear the music. That is where the rage comes from.. the loud obnoxious systems that the anger comes from, not the adds...
