Could cell phones, radar play a role in sudden acceleration?

That is the big question floating around as congress and federal investigators dig into the Toyota troubles. Electromagnetic signals are everywhere, with cell phones and other electronic devices very prominent.

The carmakers have kept much of the testing a closely guarded secret, but now may be the time to throw the door open and reveal all about whether your cell phone chat could be endangering someone elses' life.
