Saudi women - and men who support them - are tweeting updates as we drive the cars through Saudi Arabia on Friday as part of an initiative that challenges a ban on women drivers.
A large number of tweets can be seen under the hashtag # Women2Drive. Most reports indicate that women have been able to drive freely without interference from the police. As a Twitter user @ Maialshareef said after posting a picture of her ready to drive away from home: "Ready to go, I saw the police car and did nothing."
Mohammad Al-Qahtani, co-founder and president of the Association of Civil and Political Rights Arabia, Twitter: "My wife, Maha, and I just returned from a trip of 45 minutes, was the driver through the streets of Riyadh."

Meanwhile, the campaign has received some support from high profile male Prince Alwaleed bin Khaled, who Twitter ". I support the movement and freedom of choice # of my sisters in Saudi"
