Paul Fischbeck, a professor at Carnegie Mellon University and a "risk expert," noted in a release late last month that although Toyota Motor Corp. has captured the attention of the media and the driving public numerous reports linking its vehicles to unintended acceleration, driving while talking on a cell phone or even innocently walking a mile are riskier than piloting a recalled Toyota.

"There hasn't been a discussion about the actual risk of driving one of Toyota's recalled vehicles," said Fischbeck, a professor of social and decision sciences and engineering and public policy, in a statement. " I think it's important for people to realize that when you look at the actual risk of driving one of these cars, it's actually very low."
