because from the inside of the car, the whole frame of reference of the insect is also moving.

The insect is moving along with us, just as we are moving along with the earth. The insect will be inside the car as long as its relative velocity with respect to the air inside the vehicle is zero. If you open the windows, the insect may be blown off by the wind blowing through the car.

In addition to the above statements. Stand still and throw your keys in the air and catch them. Then try the same as you're walking along, The keys find your hand again right? When the keys leave your hand they alreay have the energy from your horizontal motion so that when you throw them up in they air they move in an arc and return to your hand. The fly is similar, it has the horizontal motion of the car and the air inside when it jumps up to fly.
Much like if you were on a train going at 80mph and you jumped you wouldn't shoot down to the back of the train.

because the air inside the car is moving with the car and the insect is simply flying in that moving air

Because when you are travelling at a constance velocity (or at rest) you are in what's called an inertial frame or reference. Within an inertial frame of reference you cannot tell that you are in there, and everthing within that reference (including the fly) travels at the same rate, as if the car itself was not moving.
Within an inertial frame of reference you cannot tell your moving, untill you accelerate (or decelerate) and then it becomes a non-inertial frame of reference, where the fly WOULD move at a different rate.
Imagine you are in a car travelling on a smooth road at a constant speed with blacked out windows. Without hearing the engine or feeling slight bumps from the room would you be able to tell youre moving?

Well, it's like asking why don't we feel that we are on a planet that is spinning?
People who make trains are wrestling with this so they can make a faster train but not feel it -
