It doesn't really matter. It's easily available distraction and people will end up looking on movies instead of the road all the time.
It's like with TV in your car. It's not obstructing your view on the road, it's too easy to focus attention on it thus it's illegal to have one (unless it's switched off over some speed or w/e details various countries/states implement).
>I imagine a responsible Glass user could do the same.
The problem is many users won't be responsible. Good driver who doesn't use phone when driving is focused and well trained could responsibly break speed limit very often and still drive safer than 99% of people out there. Unfortunately it's impossible to fit the law to such cases so people who pay attention are hold to the same standards as texting-while-driving morons.
Same with glass - banning it is better for everybody.
Responsible drivers, even those wearing glass, would only use it for driving related tasks, if use it at all.
The irresponsible drivers, the ones who would watch movies, would do it whether it is legal or not. Same people who text and drive even though it is illegal.

Have you used Glass? It hardly seems likely people are going to use it for watching movies on while driving - the screen is really small and in one corner of your vision.
The point is that is a possible distraction. You can only really thoroughly process 2-3 inputs per second. If something on Glass, no matter what, make you focus on it, you're down to 1-2 things, which might very well be the difference between a deadly accident and no accident.
I'm sure a lot of users would be able to ignore Glass when needed, but the majority wouldn't and that's why they're making laws.
