He needs to learn self control.

So suggest nothing in life is free protocol. you can google that.
I suggest teaching sit and wait at the door.
You can put the dog on a long line and ask sit and open the door and if he moves close the door.. open just a little and only for a short time.
If he stays sitting then you can give him a reward or a payment on good work of a treat.
This next one is over a three day weekend when you can devote the time.
Yes it does take this long if not longer to work a skill like this.

I work self control in the car as well. It going to take a few days but will help build a nice strong relationship with your dog.
Start with simple going out to the car and treat for a nice sit. walk back into the house.
Back out and sit and stay or wait open car door and close treat go inside.
You can stop at any point for the day through this preferably on a good positive note and before both of you are tired.

Two things you are teaching is self control and also that not every time you go to the car does it start and you go.
Bust this up into as big or as little of pieces as you want this is just an example of what could work as a training plan.

Ok back at it so out to car sit pen door , get in get out close door and the dog need to stay calm.. you build this till you can start the car down the road and back up or go around the block..

This is what is needed to a true phobic dog with panic attacks in cars.

SO no we go.. back out to the car
