Why is it considered haram for women to drive in Arabia? Is women driving haram in islam?

Because it is an exposure to the female in public. Drivers need their eyes to look and hence female eyes are to be watched during driving. Hence the government did prohibit driving as a closing door to fitnas and not as haraam. Not haraam since driving is to take the car from point to the other. If done as sahabiyahs and Hazrat Aisha or Asmaa r.a. did on their camels, with all due respect, then it is not haraam. Sometimes it becomes a necessity for some countries where there are insecurity that all movement can only be done in the car. But driving for a woman is not a necessity in most environment and should not be encouraged as such. One should evaluate one`s necessity and the mahrams may decide whether to teach their females to drive or not.
