I'm going to try to discuss some of the various unspoken standard rules and techniques of shidduchim dating in installments of "The Official Rules Of Dating"
First up, Opening the car door-
I try to park my car next to a walkway rather than in front of a tree or some other obstruction when I pick up a date in order to allow easy access to opening the car door. I then open the door, wait for the girl to begin to sit down, and walk to the other side of the car. I don't close the door because of the ridiculous thing that I've heard that you aren't supposed to do that because it will require you to look at her legs to see if she pulled them into the car. But hey, I try not to do anything too controversial.
As for getting out of the car, I've never had a girl who waited for me to open the door for her to get out, but that would be super weird if she did. So she handles that.
The thing is I don't really understand why we open the car door. Its not like I'm really helping you. I'm expending so little energy, it's not even worth it for you to utter "thank you." We no longer really view women as these helpless little things who can't do anything. So why do we hold onto the antiquated tradition of opening up the car door. Chivalry? I don't think that shows anything. I do it because its standard, but I find it ridiculous.
