As well built as she is ,the old 300cd I drive as a daily seems to be tested by other drivers that pull up around me on daily commutes.Question I have is Do people test their cars performance towards your own ? I find suv drivers weilding their bohemoths to stop at a traffic light just before you do just to win somekind of race who can get to the light first .Is this to test their drivng skill or is it to prove something about their car,I dont get it.I drive along at a certain pace , use signals at every light ,and stay reasonable around the speed limit ,some others have a James Bond approach which makes me think that people who are driving like this have not a road race manaic mentality,better yet, My guess its the sales guy at the dealership who after a test drive with a buyer says ,"this car is a rocket ship", after trouncing the car purposely showing the cars level of performance on public roads.
