Al Huwaider says the general consensus among Saudi women is that sons are the worst male guardians because "they feel they own their mothers." Brothers, she says, make the best male guardians. Husbands fall somewhere in between.
"In general, brothers are the best ... especially when he has a wife and is open-minded," she said. "But of course we don't want anybody, we want to be responsible for ourselves."
Despite opposition from the religious establishment Al Huwaider expects change to come eventually. In January there were reports that the driving ban would be lifted by year's end, an optimistic view that Al Huwaider has adopted.
"We feel it will happen soon. … I feel it's going to happen this year," she told ABC News.
Until then she remains part of a growing movement in Saudi Arabia engaged in the fight for women's rights.
"I'm not afraid of the government, but I'm afraid of the religious establishment -- people who think that I am trying to change the society, to make it Westernized," said Al Huwaider.
"In a country like Saudi Arabia you always have to take risks."
