It's not, GPS dashboards are dangerous as well. A lot of people are just too distractable to have these kinds of things stealing their attention away from the road. I'm all for people being distracted, but not when a) they're driving a one-ton killing machine and b) very often the things distracting them are just flat out wrong: I can't tell you how many times I've been in a car with a GPS (or iphone) and it gives completely ridiculous directions. Sometimes it's better to just switch off your targeting computer and pay attention.
