No, there are many ways to power vehicles, from electricity to natural gas to hydrogen fuel cells. These technologies already exist, and others are being developed and improved on (one example:

The only difference between many arab countries and sub-saharan africa is the oil. Once oil is gone or no longer in demand, they will return to being a poor 3rd-world region that nobody cares about.
