the air in the car would have a negligible effect on the bird.
in the reference frame of the car itself, the bird would be "pulled back"
relative to the ground, the bird would stay put, while the car would be pushed forward.
until the bird hit the back of the car and got pushed along

try putting a little toy car (hot wheels or whatever) at the center of a track that reaches lengthwise across the real car's interior
accelerate the real car and watch what happens to the toy car

which wouldn't really be a question if you knew how a plane worked?

I think things on the earth would go in that direction but they wouldn't fly off of it, because of gravity.

But it's not possible for the earth to just stop moving (it'll either fly off its track if there was no pull towards the sun, or it would get sucked into the sun if there was no force outwards) so I dunno how valid any answer could possibly be.

It's just a what if question, I know that it's not at all possible (According to current physics theories)

after taking a physics class anytime someone says anti gravity i get upset. i prefer the term inexplicable upwards force.

Now here's a real physics question. If Earth suddenly stopped rotating around the sun, would everything on it fly off of it like a giant emergency break?

If Earth stopped rotating in the first place, everything on it would fly off. It's the Earth's rotation / movement in and of itself that produces its gravitational effect.

Also, if Earth ceased moving in orbit, it would plummet into the Sun.
