I have *several* co workers who think its ok to watch movies while driving, and either put a tablet type device in the front so they could do that, or "hacked" their car that has a screen to enable it to do that, and swear that "it helps me not get tired on long drives".
After pulling my jaw back off the ground after they were trying to somehow justify watching a movie while driving on a freeway as something that shold be done, and also seeing people do things like eat food WITH CHOPSTICKS while driving, putting on makeup / eye liner while driving, having a book / magazine or paperwork on the steering wheel, holding it with two hands while traveling at freeway speeds, or all sorts of @%%$@#@$%@$# type stuff that shouldnt be done, my answer to this question is....
"A lot of people would do this while driving, a whole lot, and they would also consider themselves "in their right mind" but I wouldnt".
