driving shoes

Just a quick question as I sit in my usual Monday morning traffic...

Do you drive with the shoes you picked to go with the day's outfit? Or do you use a pair of driving shoes?

I wear my flipflops when I drive. I just can't drive in 4-inch-heels! And even when I'm in flats, I'm afraid to scuff the back-of-the-foot-part. Which makes me think I really should get a pair of those driving shoes with spikes on the back-of-the-foot-part because I must be lifting my foot when I drive so the naked back-of-my-foot won't touch the (ugh) mat!

What about you? Do you also use some sort of 'driving shoe'?
