I recognize that such a utility would make it harder for lawyers to make money, since a hefty chunk of their value-add is removed. I'm okay with that. It would be even awesomer when local laws aren't de facto locked away from public perusal through paywalls, though that probably doesn't apply to this particular case.
I honestly don't care if you're making it up. I want to know what's actually on the books. About 20 minutes ago, a mailing list informed me that Tetris has been used to treat flashbacks and Chess has been used to treat ADHD. A 5-second google was able to confirm that this isn't complete bullshit. Googling "states that make driving with a television illegal" gets me nothing but random things about driver's licenses and illegal immigrants.
Seriously. Full-text search on up-to-date records of law. That's all I ask.
Like most HNers I'm checking in on stories and commenting to the best of my knowledge while working. If I can invoice you for the time, I'd be more than happy to provide you with a properly MLA formatted list of sources.
In lieu of that, I hope you'll trust that I'm not just making this up. I do recall there's a list of at least 4-6 states that are very hard-line on this issue, and probably a majority of the states have laws prohibiting the driver watching video while driving.
