If a fly is flying inside of a car and the car is traveling at 55 miles per hour if the car should hit a tree does the fly hit the front windshield the back windshield or does it remain safe?

The fly would hit the front windsheild. Since the Fly is flying within the contained pocket of air, when the transporter of that pocket of air suddenly stops. The inertia of the air pocket continues until it stops. The fly would be a part of that pocket and would then continue forward until something breaks its momentum....I think.
