Just to add, straightline winds (not tornadoes) do not change direction suddenly. A car is very aerodynamic, and if you face into the straightline wind with it, it's a good place to be. Tornadoes on the other hand are circular (roughly). Plus subvortices inside of the tornado make for unpredictable and turbulent wind. Your car may handle the 200mph wind fairly well in one direction, but the next second it hits you at a right angle and bye bye.
