Weird

On my way in to work this morning, I was driving behind an old, teal sedan. While we waited at a stoplight, the driver threw her cigarette butt out the window. Bad. We continued driving, I was listening to NPR (note to self, time to pledge) and had the windows rolled down because it was nice outside. I started smelling gas fumes. The smell continued for a few blocks and I started watching my gas gauge, to make sure it wasn't me. I then realized it was the car in front of me. The car wasn't dripping gas, it was spewing gas. It was really gross. I switched lanes to try to pull up next to the driver and let her know she was leaking gas, but traffic prevented me from pulling up beside her. We finally reached the street where I had to make a right turn and the leaky car got in the lane to make a left turn. Even though we were a couple of lanes apart, I noticed that not only was the car spewing gas, it was also smoking. I looked up to see if the driver was looking in my direction, and I saw her roll down the window and reach for a cigarette. I started honking to get her attention and when I did, I signaled and mouthed that she was leaking gas. She nodded her head and mouthed "I know." I made my right turn and drove away as fast as I could. What was she doing throwing her cigarette butt out the window if she knew she was leaking gas??!!
