bochur24: Hello. I wouldn’t blame all on chivalry. I find it to be part of a certain respect and consideration. Have you ever had the opportunity to drive a Rov, Rebbe or Rosh Hyeshiva? I have. And I always got out and walked them inside. Was never told to. If I would have asked if its necessary, they would have said no. I just thought its the proper way to display respect.
No, no, I’m not turning girls into rabbits or whatever, but it is a sign of respect. Again, no biggie if it’s not done.
