From the way I see people still driving, it has to be. Jack rabbit starts, late on the brakes... I'm driving on a main drag in town yesterday, one of those Mizuno things is weaving through traffic behind me, finally gets to me and races around me...we get to the red light, where he's impatiently waiting and yacking on the phone, light turns green, takes off like a nut, gets to the next red light where I pull up alongside of him, light turns green...this goes on for FIVE lights. I find this to be the norm, seriously. If you don't notice it you're probably driving like the guy I described. Gas gas too high? I don't see it in people's driving habits...it's hopeless. 7 bucks, here we come.
