Living in my car near Miami Beach, petite female, feels mildly unsafe, any suggestions?

As the title says - I am currently living out of my car, alone, near Miami Beach. I am a petite female, soooo I am pretty sketched out at night, as well as unsure of places that are safe to sleep in my car without drawing the attention of police or tow trucks, etc.

Does anyone have any suggestions for good places to sleep in my car without worry of being hassled? I’m drug free, so that’s not a concern. I can easily disappear most places and not cause any troubles besides minding my own business in my car reading or playing my GameBoy. But I don’t want to get in trouble - or attacked - and would love to sleep peacefully from time to time.
