When you drop a girl off at her apartment or house do u usually walk her to her door?(specifically at night, pretty safe area). Usually i drive up and give them a hug or kiss in my car and roll out.

That's a good question, and I really don't know the answer. It can potentially be awkward either way.

I don't think there is a set rule; I think you just have to feel it out. There have been times when I regretted having walked her to the door and giving her a kiss on the cheek. On the other hand, I did it for my last girlfriend on our first date and it worked out very well.

I think the #1 thing is to feel out whether or not she is attracted to you. Expressing direct interest in a girl will lower your value to her unless A: she is already attracted to you, or B: you are perceived as being of higher value than her (like a celebrity or something).

If you've had a good date and you feel the attraction mechanism is in play, then by all means do it. If you have physical comfort built up, then obviously do it. If you like her, but you don't know if she is attracted to you, you can walk her, but I probably wouldn't kiss her. Like you said earlier, you can always hug in the car if you want.

If its a matter of safety, then walk her regardless of attraction. In fact, it probably wouldn't hurt to always give this option to her unless it is obviously unnecessary, in which case it might be weird.
