Mona Al-Sharif was detained in Saudi Arabia for driving and encouraging other women to drive by posting a video on YouTube and Facebook. She was released later.

For your information, "Religious" Saudi Arabia rulers, female sahaba, including the Prophet Muhammad's wife drove a camel.
Al-Bukhari reported from Abi Hurairah that the Messenger of Allah (blessings and peace be upon him) said:
“نِسَاءُ قُرَيْشٍ خَيْرُ نِسَاءٍ رَكِبْنَ الْإِبِلَ أَحْنَاهُ عَلَى طِفْلٍ وَأَرْعَاهُ عَلَى زَوْجٍ فِي ذَاتِ يَدِهِ“
“The women of Quraish are the best women who rode camels, they are most kind with their children and most caring for their husband’s wealth.”
Muslim reported from Shuraih ibn Hani’ that ‘Aisha (Allah be pleased with her) rode a camel, and it was somewhat defiant, so she kept on beating it, and the Messenger of Allah (blessings and peace be upon him) said to her,
“Adhere to gentleness.”
Camels and horses during that time was a means of transportation = driving cars these days.
So Saudi Arabian kings, change your preposterous laws and give women their rights back -- rights originally given to them by Islam.
