Contrary to public opinion, Sudden Unintended Acceleration (SUA) is not a new phenomenon, nor is it limited to Toyota products. We have been investigating these accidents for almost thirty years. While many of these situations can be attributed to pedal mis-application, there are in fact real occurrences of Unintended or Unwanted acceleration.There are some telltale pieces of evidence that can prove your case if found and properly documented. This is also another area where the downloading of an Event Data Recorder can provide useful information, if it is properly understood. One critical item that you will always want to acquire in any unintended acceleration case is the shoes that the driver was wearing at the time of the incident. Get them and place them in a large ziplock style bag as quickly after the incident as possible.
