You have to be handsome...
To get away with not actually having conversation with a woman and for her to fall for you.
If I just stared at woman whom was initial interested in me she would be put off. Put off to the point of probably thinking I was cognitively challenged or a rapist.
I get it, it's a movie and the scenes were trying to convey some mood or emotion. A little writing could have made Irene's and the Driver's relationship filled out.
The idea of guy meets girl and in very little time is love to the point of taking on the risk of helping her ex con baby dady took me out of the movie.
Just my opinion though.
