The issue appears to be linked to skipping the door animation while exiting.
If i get out and let the closing animation play, upon getting back in my character will close the door every time. If i skip the animation and then get back in my character does not close the door automatically ever. IF however i close the door first, and then get back in i will automatically close the door.

Inconsistent at best, downright dangerous at worst.

Many players don't actually realize/care that you can let the door close on exit and will just get out as quick as possible no matter the situation, often skipping the animation.
Which leads to most cars having doors left open on exit... Which leads to players getting back in and their doors not closing automatically... Which leads to players having to find the 'close prompt', or just say F it and leave them open... Add doors now having physicality... Which means those doors now clip something at speed and the whole car spins out or causes a wreck.
Multiply this by every squad and every single time you get in and out.
It's a behavioral mess that will get many people killed over something stupid.

We just need consistent and simple door behavior and it seems like a silly issue to continue to have.
I'm including a short video to make it as clear as possible.
