The fly floats in the air. The air in a moving car more are less travel with the same speed. The fly floating in air inside car does not hit on the sides of the car. While travelling in open lorry, if you throw a ball vertically in the air, the ball reaches your hand again, even the lorry moves. This is because, the ball also got the momentum to travel along the lorry while it is in the air. The will work out for certain heights only.

When the car accelerated a force acted upon the fly to bring it to the same speed of the car. Whether this was the window, or the air around it, it doesn't matter. Once moving, it will remain in motion unless acted upon by an outside force. If it jumps out the window it will experience drag from moving so quickly (when you stick your hand out the window, the air is stationary, it's you who's moving). Or if the car stops suddenly and the fly is flying around the car, it will likely hit the windshield as it continues to move while the car stops.

The fly is moving along relative to the air inside the car. The air inside the car is moving along with the car. Unless you open the windows and allow the system of air inside the car to interact with the system of air outside the car, the fly couldn't car less about the speed of the car. It knows it is inside air that happens to be inside something else, it doesn't care about the something else.
And it really has nothing to with momentun, inertia etc on the part of the fly. It only has to do with what frame of reference the fly is moving relative to. It is moving relative to the air mass--not the car. Then one can say the momentum and inertia of the air mass is a factor. But, still not really for the fly. Remember: It's all relative.

The car is a moving environment. The flies are part of that environment. They would be affected by acceleration or deceleration, but not to the extent that they would strike any part of the car.
There is no such thing as a stationary object on earth, since the planet is moving at a considerable speed in its orbit around the sun, and the sun itself is moving in the galaxy. All speeds are relative.
Incidentally, if you open windows in the car, there will be wind effects and all bets are off.

hmmmm.. open the windows.. let in the outside air.. which has NOT been traveling at the speed of your car .. and see how well the fly can get around then!!

Same reason you don't hit the windshield when you are riding in a car. They are moving at the same rate as the vehicle.

First I recommend you get a dictionary.
Second, I recommend you get a science book.
Third, I recommend you read them both.
An object in motion tends to stay in that same motion unless acted upon by an equal or opposite greater force.

because the air in the car is moving with the car...

because I opened a front window and a back window on the oposite side and the air sucked that pest out! ;)
