Device needed to read texts and emails while driving

Now this may not be the best idea for those that are driving a car, but it would be less dangerous than what everyone is doing now.

Most Blackberry owners read and write emails while driving. Dangerous huh?

Imagine the heads up display in Pontiac and BMW cars repurposed as a text displaying bluetooth device. The Blackberry would connect via bluetooth and be used as an external display device for showing emails and text messages. This way, drivers can keep their eyes on the road and read messages at the same time. I know, not very safe, but it has to be safer than what people are doing now days.
