Now, that would be a great idea!
I think you guys are forgetting that they haven't invented a light yet that can tell if only the passenger is playing with the screen. My girlfriend and I had the same disscusion.
This whole "lock out the navigation system if you are moving" thing is the reason I will never purchase a lexus again. Don't get me wrong, I generally love my car, but any company that impliments such a stupid system obviously is (1) more worried about what the lawyers say than the engineers and (2) is out of touch with the needs of their customer base.
I can put a Garmin, TomTom or any other GPS unit in the car and use it when the car is motion. Why not the built-in lexus one? Older nav dvd's had a bypass code you could enter to enable the unit all the time. They removed it.
