In-Car Navigation Systems Too Distracting?

Lam1969 writes "A survey released by an insurance company shows that drivers with in-car navigation systems are more likely to lose concentration than drivers who unfold a map while driving. From the article: 'One in 10 motorists with navigation systems set off on their journeys without bothering to program their route, and more than half admitted that they then had to take their eyes off the road to input the details while driving. Nearly one in eight did not even bother to check out a route they were unfamiliar with and simply relied on the technology to get them to their destination.'"
