How long before they mandate all cellphones go into airplane mode when moving in a vehicle? Basically no radio means no text/talk/http while driving. The ones playing bejeweled will still crash though.
I like the idea, but what if you're a passenger in a car? You should still be allowed to text and/or talk on the phone. Most states are hard-up for cash these days - just dramatically increase the fine for texting/talking on the phone while driving. $1000 for a first offense is a good start.
