The Unintended-Acceleration Story |
NO CATALOGUE of this sort would be complete without an account of 60 Minutes's 1986 attack on the Audi 5000 perhaps the best-known and best-refuted auto-safety scare of recent years. The Audi, it seemed, was a car possessed by demons. It would back into garages, dart into swimming pools, plow into bank teller lines, everything but fly on broomsticks, all while its hapless drivers were standing on the brake or at least so they said.

Ed Bradley: Six-year-old Joshua Bradosky liked to open the garage door when he drove home with his mother. The Reverend and Mrs. Bradosky told us what happened after she let the little boy out of the car to open the garage. Kristi Bradosky: I got back into the car and put my foot on the brake to put it in drive, and the car surged forward, and I saw that I was going to hit him. So, I put my foot on the brake, but it didn't stop the car. (Crying.) It pushed him through the garage. And we had a panel partition, and it went through the partition. He went through it. (Crying) Bradley: You put your foot on the brake? Bradosky: Mm-hmm. 60 Minutes, Out of Control, 23-Nov-1986, in Peter W. Huber, Galileo's Revenge: Junk Science in the Courtroom, Basic Books, 1991, p. 57. |
I recently watched in fascination as Ed Bradley reported on the CBS-TV
show "60 Minutes" that the 1978-'86 Audi 5000 sedans can treacherously
launch themselves like misfired missiles when their automatic
transmission levers are placed in drive or reverse. This phenomenon
labeled "unintended acceleration," has allegedly been responsible for
several deaths, including a particularly poignant one tearily
documented on the show in which a pretty young mother crushed her
young son against the back wall of a garage. The segment included
testimony from several victims. They decried Audi's suggestion that the
trouble lay not in a mechanical flaw but in driver error.

Today, Audi is reportedly defending itself in more than 140 different suits, and damage claims are in excess of $5 billion. [...] The largest suit now pending against Audi is an Illinois class action, ostensibly representing 300,000 or so Audi 5000 owners.

Audi began selling cars in America in 1969 with unit sales of 7,691 and they grew steadily peaking out at annual sales of 74,061 units in 1985. From there sales plummeted to a low of 12,528 units in 1993.

Even some valet parking garages have posted signs that they will not
accept the Audi 5000 with automatic transmissions.

"If a driver unknowingly steps on the accelerator pedal and continues to push on the same pedal because he or she believes it is the brake pedal," the car will accelerate and the brakes will seem to have failed. "[I]t is reasonable to expect that drivers would be more likely to step on the wrong pedal the first time after entering the car, or when their body is twisted out of normal position to look to the rear for backing up," which explains why most incidents occur in cars backing up from rest. In a number of cases NHTSA engineers found direct evidence that drivers had been stepping on the wrong pedal. They discovered one projecting part of the gas pedal broken off after some accidents, and they found electrical switches underneath the accelerators crushed by the desperate pressure of the driver's own foot. [...] In December 1988, Transport Canada had released its sudden-acceleration study, which concluded: "The present study, and all others known to Transport Canada, confirm that sudden acceleration ... occurs as a result of driver error." The Japanese Ministry of Transportation released its final report in April 1989. After analyzing 1,108 sudden-acceleration incidents and performing experiments on fifteen different cars, the ministry came to exactly the same conclusion: no defect in the car causes both high engine power and loss of brake effectiveness. Sudden acceleration, in short, was a problem of lawyers, not of cars. Peter W. Huber, Galileo's Revenge: Junk Science in the Courtroom, Basic Books, 1991, pp. 68-69. |
What 60 Minutes Did Wrong |
The "60 Minutes" story starred a mother who had run over her six-year-old son [Joshua Bradosky]. On the air, she insisted that she had had her foot on the brake the whole time. When her $48 million claim came to court in Akron, Ohio, in June 1988 the investigating police officer and witnesses at the scene testified that after the accident the distraught mother had admitted that her foot had slipped off the brake. The jury found no defect in the car.

"60 Minutes," in one of journalism's most shameful hours, gave air time in November 1986 to a selfstyled expert who drilled a hole in an Audi transmission and pumped in air at high pressure. Viewers didn't see the drill or the pumpjust the doctored car blasting off like a rocket.

60 Minutes [...] showed a filmed demonstration of how an Audi, as fixed up by, yes, an expert witness testifying against the carmaker, could take off from rest at mounting speed. The expert, William Rosenbluth, was quoted as saying that "unusually high transmission pressure" could build up and cause problems. "Again, watch the pedal go down by itself," said Ed Bradley. Bradley did not, however, tell viewers why that remarkable thing was happening. As Audi lawyers finally managed to establish, Rosenbluth had drilled a hole in the poor car's transmission and attached a hose leading to a tank of compressed air or fluid. The tank with its attached hose was apparently sitting right on the front passenger seat of the doctored Audi, but the 60 Minutes cameras managed not to pick it up.

And in the Audi, as in any car, the brakes will easily overcome an engine even at full throttle; press the brakes hard, and the car will come to a stop whatever the engine may be doing. So during the Audi accidents the brakes must somehow have failed. And, yes, the drivers are all certain they had a foot on the brake, as they assure "60 Minutes": "The foot was on the brake so hard, Mr. Bradley, that I had a shin splint. The entire foot was black and blue from pressing so hard on the brake."

[M]y race-driving partner, Price Cobb, did some personal testing back then and heres what he has to say. "60 Minutes did an expose on the Audi saying that these cars had a run-away problem and that somehow the car went berserk and gave itself tons of power and made the brakes inoperative at the same time. So I took a new car off the showroom floor onto the highway and accelerated up to the speed limit, THEN I floored the gas pedal AND applied the brake and still brought the car to a halt!"

[T]he Audi 5000 with its 2.2-liter, five cylinder engine developing only 110 hp simply does not have enough power to override its brakes. (Drivers involved in the incidents swear they are standing on the brakes. Audi has found no instances of brake failure in autos it has examined.) Who's right? Will an Audi 5000 outmuscle its own brakes? I borrowed a 1984 Audi 5000, floored the accelerator with my right foot and stepped on the brake hard with my left foot. Then I moved the transmission from park to drive. AND THE ENGINE STALLED! It lacked sufficient power to override the brakes. According to my brief test, for unintended acceleration to occur, two independent systems fuel supply and brakes must fail simultaneously and [after the accident] somehow return to normal. Audi says it went even further. In demonstrations for both CBS and NBC, it made full-throttle acceleration runs to speeds between 30 and 50 mph and then, with the throttle on the floor, stopped the car with the brakes. Brock Yates, Audi's Runaway Trouble With the 5000, Washington Post Magazine, 21-Dec-1986, in The Risks Digest, Volume 4: Issue 33 catless.ncl.ac.uk/Risks/4.33.html#subj7 |
Tests performed by Road and Track in 1986 repeatedly showed that no matter how much throttle was used, the engine simply was unable to overpower the brakes. It is a simple fact of automobile production that the brakes have more power capabilities than the engine. This is true of all production cars, and even more so in the higher performance variants. If the drivers of the 5000 truly were holding down the brake pedal, and the engine still could accelerate the car to any degree, nevermind accelerate out of control, then that would suggest massive brake system failure. This however was not found, as mentioned above as all cars were found mechanically functional with no major systems damaged.

[T]he phenomenon of "unintended acceleration" is not new. The problem has occurred in a variety of autos with automatic transmissions. More than 2,000 complaints have been made about General Motors models built between 1973 and 1986. Owners of Toyotas, Renaults, Mercedes-Benzes and Nissans have also reported unintended acceleration incidents.

"60 Minutes" never even acknowledged the final U.S. [NHTSA] findings, it did grudgingly note identical conclusions of an earlier, blue-ribbon study, and then proceeded to rebroadcast inflammatory videos from the earlier segment.

CBS continues to brazen out even its egregious Audi segment. Ed Bradley was a guest on Larry King recently when a caller praised 60 Minutes in general but politely suggested it might want to apologize for faulty or mistaken stories like those on the Audi and on Alar, the apple spray. "First of all, they're not mistaken. Secondly, they are true," Bradley replied with some heat and more redundancy. He reminded listeners that among the Audi victims the show had spoken to were a policeman and a state auto inspector, supposedly unfoolable about such matters. "It's not a figment of our imagination. It actually happened, whether you believe it or not." Hewitt, on Crossfire, defended the Audi show in a different and, if truth be known, contradictory way. If there was really nothing wrong with the cars, he asked, then why had Audi recalled them after the 60 Minutes episode? But the point of the main recall was to add an "idiot-proof" device that kept drivers from shifting into gear unless their foot was on the brake. If you accept Ed Bradley's theory that their feet were on the brake all along, that fix should have been useless.

[The American Lawyer] Editor-in-chief Steven Brill cites "the media's almost comic double standard when it comes to holding itself accountable as opposed to holding the rest of the world accountable."
