Is it normal that she acted like this??

I was waiting at the bus stop when this girl (I've known her since kindergarten)came across me while driving her car. She offered to give me a lift and I accepted. Once I was in the car with her, she took me to a lonely parking lot and just stood there, silent, looking at the front. Sometimes she turned her look at me in a flirty way. I didn't move and asked her to take me home, and she finally did.
