Or maybe you just shouldn't watch terrible Micheal Bay films.

But seriously, what are you basing this on? Film sets aren't chaotic at all. Independent ones - maybe. But 100 million dollar pictures are meticulously ordered and have several ADs keeping to schedule. Source: I work in production.

Crossing the line is also not as much of a problem as you make out. Everything is super storyboarded, or a DP will no instinctively if the 180 rule has been crossed.

I also work in production, and sometimes as an AD, mostly as sound mixer. I like a smooth well-oiled machine too, but even with previz, boards, and continuity people mistakes arise.

I don't sub to American Cinematographer any more, but that's a great place to find DP horror stories about 2am match mistakes and suchlike.
