At NO time during this entire movie does that convertible's top ever get put up.

Even when Louise leaves work at the beginning of the film and it's clearly been raining outside, the f'ing convertible's top is down! A normal person would freak the hell out at the realization that their vintage interior has just been rained on, but not Louise! She just hops right into that car and drives off without a worry in the world and with zero acknowledgment of the fact that she's sitting in a soaking wet seat.

Then Thelma & Louise drive cross country with the top down 100% of the time. This would be awful for so, so many reasons. The dirt and debris you'd get in your eyes. The sunburn. The constant road noise. That would all get real old real fast!

And another thing: Why do moviemakers always insist on using ridiculous amounts of illumination on actors when they're driving at night? It's so unrealistic it becomes distracting! Ridley's got both of these women (who are supposedly fugitives running from the law, no less) blasted with bright lights as they drive through the pitch-black desert. That makes sense! Do directors really think we need to see the actors' faces in their full glory at all times in order to know who we're looking at? We're not dumb. At the very least TURN THOSE OBNOXIOUS INTERIOR LIGHTS DOWN BY HALF.
