yah...I’ve heard other speculation that it could be an EMI problem too. What if your blackberry ring tone goes off, just as you pass near a power transmission line, going exactly at the shift point from 2nd to 3rd....and so forth. Pick your combination.
The point was that you are asked to turn electronic devices off on an airplane so the EMI doesn’t interfere with the aircraft’s instruments. Why wouldn’t the computer in your car, that is 2 feet away from your cell phone and not even close to being EMI hardened, ( PC, IPos, crackberry, et al); be subject to the same kind of EMI??
Scary prospect if the computer really has that much control over the car....
You are required to do so, but repeated testing has NEVER supported the idea that any interference actually occurs.
It's a "what if" regulation with no basis in fact.
