"The U.S. Department of Transportation has analyzed dozens of data recorders from Toyota Motor Corp. vehicles involved in accidents blamed on sudden acceleration and found that the throttles were wide open and the brakes weren't engaged at the time of the crash,"

It doesnt say how many throttles were wide open out of the "dozens" that they tested. If two throttles were open out of 3-4 dozen cars... that doesnt mean much.

And which cars did they pull the black boxes from? Probably ones that they already knew were driver error from other evidence.
