Can other people see me?

So, on the way to work today, other drivers kept riding on my ass--and I was going over the speed limit! Having only slept a couple of hours last night for some reason, my mind was/still is going to weird places. I thought, 'Hmmmm, maybe the other drivers can't see me! Why else would so many people be assholes on the road today?'

Then again, maybe I was just surrounded by assholes today, and that's all there is to it. *sigh* It's not even 10:30am yet.
