Why does an object that falls off of a vehicle in motion travel backwards? If the vehicle's inertia is going forwards, and an object falls off, shouldn't it travel forward?

Example: a piece of luggage falls off a car traveling 70 km/h and the luggage travels backwards as it hits the street and bounces up multiple times.

I'm confused, /sci/.
Newton's third law says for every force there is a force in the opposite direction.
But why can I open a door then?
Shouldn't the door have a force in the opposite direction too, so that it doesn't move?
