I did once. I was going down a hill with a stop sign at the bottom of the hill. I was going really fast, so I had to stop real fast too. So I mashed on the brakes, and happened to catch the gas at the same time. I had no idea what was going on, so I didn't even think to put it in neutral or use the e-brake. I ran the stop sign and very nearly side-swiped someone. But its no problem now that I'm aware of it. Just a little warning for ya.
Also, this may not apply to your pedals covers (mine are kinda cheap) but when my shoes are wet, I always feel like my feet are gonna slip off the pedals.
