At the bottom of the article: A small box called an Event Data Recorder (EDR) is the key. It records speed, throttle, engine RPM and brake status. Toyota has the only software able to decode the data inside, but refused the Eves' plea for help.
"Right from the start, Toyota has used nothing but a bunker mentality about trying to help us," Ron said.
But after Senator Maria Cantwell saw our reports she questioned the North American CEO of Toyota, Yoshi Inaba during a Senate hearing and he promised to unlock the answers on the Eves' EDR.
snip: Toyota's analysis of the Eves' EDR includes data from five seconds before and one second after the crash. The five seconds of pre-crash data show Chris's truck traveling at about 75 miles an hour with no braking. After the crash, the data show a velocity change of 177 miles per hour. That number is meant to show the severity of the impact, but experts say the numbers are impossible.
Most new GM's have had GP for several years included with OnStar. It's in my 09 Cobalt. I have no problem with that. Stolen cars are easier to find. Lost and need directions. hurt in a crash and in shock, emergency crews can still find you. Etc.
