I moved my character's head around and half of the entire cast was. Right when the cart stopped to get the prisoners off I saw there was no horse on mine, and the other cart was completely missing. I thought it was over once the dust cleared and turned back to my laptop, waiting for the character creation to show up. (small cart killing you bring up a few bad memories? Anyone? Perhaps a skull or bucket?) I face the tv and I witnessed the most hilarious thing (at least to me anyway) The horse in the carriage my character was in, was spassing out of control but the cart was still going, and then a few seconds later the cart jolted and sped up on top of the other cart! Amazingly no one died from Skyrim's weird collision laws. And all of a sudden I see weird patterns of flashing lights on the screen at the corner of my eye.

So this is like my one hundredth play-through (give or take a few more ), and I look away for about 10 seconds. I look on my laptop, chat a bit but also play Skyrim at the same time. I had a similar experience to what frostspiderman had.
