In this particular case, 150-foot skid marks indicate that the driver was trying pretty hard to stop. No doubt there are accelerator-brake confusions in many of these cases, especially with older drivers. I'm really hesitant to say they all are in that category. Investigators need more "black box" info to see, for example, whether the accelerator and/or brake were being pressed in the seconds before an accident.
