driving w/o a dashboard

I was wondering, is it safe to drive around with the entire dashboard off? I want to do some work behind the dash but don't want to keep having to take it off and put it back on, I just want to take it off, do what I can when I have time, then put it back on when everything's done.

As long as the underpinnings don't create a distracting or vision imparing glare on the inside of the windshield, i'd say your fine to drive with it off.
