Startup Idea : FUN App while driving.

I want to solve the entertainment that is in a car while driving. Right now all you can do is listen to music and call people. I want something (like a trivia game) that you could interact with while driving. you can also communicate with other players. you can have a private game or play it with other people close by. It will make traffic fun and it will engage your mind while driving. Also, your kids can play it - we can have a Disney trivia game that is not linked to other cars and it is just easy to play while using the voice this way they aren't just staring at the ipad or iphone. [Or an app where you can have discussions on certain news reports - or you can create your own discussion board. maybe have a computer relaying the responses so it doesnt get backed up. - this one is just another idea playing off the previous one]
