No experience yet, but last week I was pulled over because my windows are tainted. when the cop talked to me he was very curious about my setup. "Are you able to watch movies with that?" or "You know it's illegal to watch movies while driving" and questions like that. I know that insurance companies do have a problem paying damage if they found out you are able to..
Mercedes Benz does disable video standard (in front) while driving.
@guino:
No rush, it's just how I think about it. I know that I don't watch while driving, but I think it's a good feature. what about disable the front monitor and play video on the headrest monitor? There are more important updates to expect
