Does Your Driving Show you're a Christian?

Tonight, on my way home from seeing the amazing Chrissi Culpepper sing at Night Sky, I found myself driving behind my neighbor. It was dark and he couldn't tell who was behind him, but I knew his car. As we went along he zipped down the road, and cut in front of a truck as he turned toward our street; it was startlingly close to distruction.
My first thought was, I wonder if he's a Christian, then I thought, his driving suggests that he's not. You see he lives about 12 doors down for me, and while I pass his house everyday, I've never actually met him, so I don't know. But, I started thinking what does my driving say about me? Does it reflect HIM? I know that sounds a little strange, but we're supposed to reflect Christ in everything we do, so what does everything we do say about us? Others are watching, what kind of Christ are we showing him? In the way that we talk, act, drive, smile, dress, spend our money, our time. It should all be a reflection of Him...
