Saudi women activists are hopping behind the wheel again, with the #Women2Drive campaign gearing up for President Obama's weekend visit to Riyadh.

Saudi Arabia is the only country in the world that prohibits women from driving and 70 members of the U.S. Congress penned a letter to Obama this week urging him to raise critical human rights cases with King Abdullah.

Amnesty International also weighed in, urging the president to bring along a female Secret Service agent as his driver while in the Kingdom.

"President Obama should show his support by bringing a female Secret Service driver with him to the country," said Sunjeev Bery, the group's Middle East North Africa advocacy director.

Regardless of who's driving the president, there will be plenty of women on the road during his visit. At least 100 women have defied the law and driven in Saudi Arabia Since Oct. 26, 2013, according to campaign organizers.
