Did you talk to any Saudi women about this?
Overall, there seemed to be a rather pronounced divide between the cities and the country side: In the cities you did see the occasional woman without hijab, some women working (particularly in the hospitality industry), and a few women driving (though still not many). Meanwhile, in more rural areas tradition strongly prevailed. So none of the things I mentioned are really commonplace yet (not even in the cities) – it's just that at the very least they're legal now and people (women) are making their first baby steps towards enjoying their newfound freedom.
