First of all even if saudi allows you to drive. I wouldnt recommend a lady going

by herself across saudi arabia, not only that I wouldnt recommend anyone goin

by themselves, its too risky. Every now and then we get to see car crashes and

big accidents, most of which people were found dead. Secondly, just by driving

on the roads in qatar, u must know how fast they'd drive over a highway. 

Now the part about Saudia doesnt allow women to drive. 

Here are  more details about Saudi women drivers:

 

RIYADH, AUGUST 21 - A 19-year-old Saudi Arabian woman, Myriam, has undergone a successful sex-change operation in Jeddah and now, with her new name of Khaled, aspires for just one thing: a driving licence. Saudi Arabia is the only country in the world where women are banned from driving, added Okaz daily, reporting the news today. "The first idea that came to my mind a few hours before the operation, was to have a driving licence," Myriam/Khaled told the newspaper, adding she was encouraged by her family to have the operation. Sex change operations are rare in ultra-conservative Saudi Arabia. "I entered (the hospital) with the abaya (traditional women's garment) and I came out with thub, ghotra and ogal, the white tunic and hat worn by men," Myriam/Khaled said. 

 

It's always the small things that make big differences.
