If you're driving your CyberTruck™ 100mph with the windows up, and there's a fly flying around inside your CyberTruck™, and then you crash into a concrete wall head-on, what happens to the fly?
I really like answer three but my inner nerd can't help twinking out the correct answer. The fly is traveling at the speed of the vehicle but with no wind resistance, therefore if the vehicle comes to an abrupt stop the fly will maintain inertia. However, because of the fly's lack of mass it would lose velocity very quickly and would most likely be able to divert it's flight path away from danger. Assuming of course that high velocity debris from inside the cabin didn't collide with the fly. But also, Fuck You
Wind resistance counteracts inertia. 100 m.p.h. winds would tear a fly's wings off and rip its body apart. In a vacuum a fly would have greater inertia due to a total lack of atmospheric resistance, but no ability to control or divert it's flight patterns since wings are useless without air
More or less the same thing that happens to the dust that is suspended in the air.
It depends on where it is and what's going on. It also depends on how fast that car deceleration is going. If it's a 1/4" sheet of concrete held up by something on the ends, you would not necessarily expect a full stop right at impact.
There is a difference between a stationary car being hit with a wall at 100 mph and a moving car hitting a wall at 100 mph. But even with a stationary car being hit, the deformation of the front with windshield (if it remains intact) is going to cause a pressure wave that pushes on suspended objects. You have to compare that to the inertia of the object. Does the compressed air create a sufficient resistance to prevent the fly from hitting the windshield? If it's at the back of the car and a light fly, I would think so. If it is a heavy fly near the front, it is more likely to hit the windshield.
You could probably math it out, but it is a fluid dynamics question.
Hard to troubleshoot what you don't understand about compression and air.
You know those "drop zone" towers? The reason they slow down is because the air column under the platform compresses and acts like a cushion. Same concept will happen with a fly or fleck of dust in the air of a car. Wham! The pocket of air is travelling at 100 mph, smashes against the front, momentarily compresses to a degree that can cushion suspended dust from hitting the front, but not a 150 lbs human. A fly is somewhere in that range, somewhere closer to dust. Will it be cushioned? Or will blast through the compression wave? Just like "drop zone" there is a balance in the equation that determines whether the air cushion is sufficient.

It's basically riding along in a pocket of air.
