It is a scary thought if this is anything to do with the reason for sudden acceleration.
Toyota's Worst Nightmare: EMI-Linked Unintended Acceleration - GearlogElectromagnetic inference (EMI) as a cause of Toyota's unintended acceleration woes: That's the latest allegation. And one that Toyota quickly rebutted, which is not the same as saying successfully refuted. EMI is scary in theory: The electronic devices we carry with us such as cellphones, laptops, and iPods emit radio waves that might interfere with cars, pacemakers, or the airplanes we fly in. This potential cause was highlighted today in a press conference by Tom Murray, an Ohio lawyer who's filed dozens of unintended-acceleration lawsuits the last two decades.
EMI problems, if they exist, are hard to prove or disprove. An unintended-acceleration glitch that happens every 100 million miles of driving could be dangerous on the whole to a handful of motorists, but the odds are dramatically against it affecting any one car. For most of the 20th century, the functions of a car were purely mechanical: With a little training, you could look at a carburetor, throttle cable, or hydraulic brake and figure how it worked. It's different where a bunch of wires go into one end of black box and the other end connects to an actuator or still more wires. Statistically, x-by-wire systems (drive-by-wire, brake-by-wire, throttle-by-wire, eventually-steer-by-wire) are far safer than mechanical systems. That's why planes are now fly-by-wire, and you don't see them falling out of the skies. But it's also hard to prove safety of electronic systems to critics or the public, especially when your credibility is suffering.
