Being a female, I do drive with flip flops on. However I do catch myself taking the right one off while driving. And driving in heels is tricky sometimes no matter what height the heel is (i almost always take right heel off while driving).

And, not to long ago there was a young girl 18 maybe? driving her younger brothers to a baseball game, flip flop got stuck, she swerved into on coming traffic and the car got t-boned. Killer her brothers in the back seat instantly.

It's sad that it happens.
