But despite this shift, Saudi women are still held up by restrictive guardianship laws where men in their lives must give approval before they get basic things such as renting a house.
Twitter exploded with videos of Saudi women driving for the very first time, highlighting their experiences with the hashtag #saudiwomendriving. This move was announced previous year in September, as part of the Kingdom's effort to remove the country's reputation of repressing women's rights.
Just last month, the pendulum appeared to swing away from the latter when several prominent women's rights activists who were at the forefront of calls to lift the driving ban were arrested.

"There will be more cars on the road", Khalid Al-Falih said in Vienna, where he was attending an OPEC meeting.
The lifting of the ban is also creating opportunities for women to make money from driving.
