Countries such as Sri Lanka ban GPS device altogether, making it impossible for colleagues of mine such as Symbian-Lifeblog and Mobile Royale to obtain NSeries and ESeries phones for review, but Germany has implemented a law which doesn't allow usage of GPS units while driving, and that includes GPS in phones.

I believe this makes complete sense, as it will distract your driving. The problem here is that mobile phone GPS units aren't tweaked to lock a user out when a car is in movement, there the German courts had to ban phones with GPS in cars altogether, which is reasonable. It's the manufacturers who have to disable usage when it detects the vehicle in movement, but it will be very annoying if it's not the driver using it.

It seems that there will have to be a smart recognition software for this, such as only including this function when the GPS unit is in a car holder. This might might be useful as when a car is in motion, the driver won't try to hold the phone and control it, now if the phone is in the car holder, the phone will lock itself until the car stops, rendering the driver incapable of using it. If there is someone else operating the GPS unit, they can do it outside the car holder. It's tricky, and I'm not very creative. We'll have to see what the manufacturers bring.
