Sat-navs impair driving?

Interesting piece of research that has picked up lots of media coverage today.  Researchers at Lancaster Uni are suggesting that using sat-navs actually impairs driving performance, as well as sometimes taking us the wrong way.

As the directions get more complex, we are likely to speed up, swerve more and not detect pedestrians.

Seems to point to some good basic human factors guidance on ensuring that the directions remain simple.
