Sudden Acceleration Syndrome Hypothesis

SASH - Sudden Acceleration Syndrome Hypothesis"
Sudden Acceleration Syndrome (SAS) has been something that has plagued all automatic car makers for many years. In fact, the current shift interlock systems, where you need to depress the brak...e to shift out of PARK was born to help prevent SAS.
Unintended acceleration resulting from pedal misapplication as a driver error - wherein the driver presses the accelerator when braking is intended. Pedal misapplication may be related to pedal design and placement, as in cases where the brake and accelerator are too close to one another or the accelerator pedal too large.

About these two possibilities—drivers malfunction or electronic malfunction
Proponents of the “driver pedal error” hypothesis contend that where no physical evidence of a failed electronic component is found after the event, there could not have be an electronic malfunction and therefore the only plausible explanation is that it was the driver that malfunctioned.
The sudden acceleration incidence rate appears to vary widely between vehicles of different manufacture and between vehicles of the same type but different model years. This strongly suggests that whatever the factors are that cause sudden acceleration; these are related to the driver.
There's been a recent poll on who drives a manual or automatic car, with results split almost 50-50.
Putting aside all other comparative cost/benefits of the two transmissions, which do you generally believe is the safer to drive?

*Googling reveals fierce debate on the subject. What prompted this poll was talking with a copper about an accident and what he called SASH - Sudden Acceleration Syndrome Hypothesis - when a driver in an automatic slams down on the wrong pedal, surging the vehicle forward and causing a collision. However some online commenter makes the point that since manual drivers have something else to thing about their attention is focused on something other than the road.
