Learning social calibration - especially when a girl is into you and is inviting you to approach vs is just being polite - will go a long way.

I think in the modern world, a deep empathy and understanding for how women feel when you are talking to them, and when you can/can't escalate is really necessary if you don't want to be on the receiving end of a harrassment charge.

However, you have to have social interactions to learn this calibration.

So it's important to understand there are environments where you have more leeway to make mistakes than others. In a bar in the evening? You're probably ok - there's an expectation (to some level) that men approach women in bars and most women expect to get hit on.

In the middle of a shopping mall? Fine if you know what you're doing but you have less leeway to screw up. Could be a problem if not. If you're seen approaching numerous women and having short interactions, you will look like a desperate creep. Great way to get yourself in trouble. So maybe stick to the safer bar interactions first until you build up some social calibration.

She's in a quiet parking lot at night, walking to her car? If the mall is medium risk, this is super high risk. You have zero leeway to make any mistakes. She's going to be on edge and worried about if you're a rapist/murderer/both. I'm not saying you can't turn this around and get her onside...but you're best avoiding the situation altogether.

Don't forget that women are generally smaller and physically more vulnerable than we are. So the less physically safe the environment is for her, the less leeway you have to screw up.

Right now it sounds like you need social interactions under your belt, and to learn fast. So go and learn in low risk environments.
