One time I was driving on the I-5 a ways north of Seattle late at night. There was a stretch of freeway with virtually no lighting, surrounded by trees, and there were no cars in sight in either direction. I completely lost any sense of speed, and when I looked down at my speedometer I was going about 120 MPH. Fortunately I had the presence of mind to not slam on the brakes and to let the car slow down naturally, but it was scary to realize how dangerous my speed was, and I was lucky a deer didn't tumble out of the woods.
