Yeah, it's really not a good idea to turn the stereo up so loud that you can't hear, either, even though a lot of people, myself included, do it all the time (although in a Sprinter with only the dash speakers, that's not an easy thing to do without blowing the speakers). Sense, common and otherwise, tells you that it's not a good idea to drown out or block ambient or external noise that may be important, like sirens, honking horns, or screamed pleas to stop backing up over someone or some thing.
The really ironic thing about hand-held cell phones versus hands-free talking is, every study that's been done on the issue show that both methods of using a cell phone result in exactly the same diminished alertness and response times. The rationalization is that talking on a headset is functionally no different than talking to passengers. But talking to passengers
also results in the same diminished alertness and response times, and isn't that funny. If the cell phone laws were based on actual fact, we wouldn't be able to use them at all while driving, with or without a headset. But lawmakers faced too strong an outrage from constituents to go that far. That's also why we don't have helmet laws when driving or riding in a car, despite helmets being far more of a factor in saving lives than seat belts.
As for windowless vans, a van with no windows is called a
tank in the Army.
Most of the window tint laws are mainly concerned with the windshield and the two windows to the driver's immediate left and right. The windows behind the driver are less affected by tint laws, with those windows mostly being allowed any amount of tint you like or darker tint than the front windows. About one-third of the states allow them to be blacked out completely.
As for that four course meal, while there are no state laws that I'm aware of that specifically prohibit eating while driving, there are plenty of much broader laws against distracted driving. If an officer determines you are a danger to others due to the distraction of eating, grooming, using music controls, talking to passengers, drinking, smoking, etc., they can ticket you for either distracted driving or reckless driving. Lots of examples of that to be found. Last year in Kentucky, the State Police set up checkpoints, like the sobriety checkpoints, to look for people driving while eating, even though it's not illegal. It was to "educate the public" about the dangers of distracted driving. Meanwhile, police response times to actual emergencies continue to grow. <snort>
