People have body language and so do cars. When you ride a bicycle, as I do, you notice the body language of cars. I noticed one yesterday. I was holding up his progress, and I could tell he was restless back behind me. As soon as it was clear up ahead, his engine roared and tires screeched and he was off to beat me up the road and show me who was boss. Although he had 200 or more horsepower and I am not as strong as even one horse. But this guy acts like it's something great that he can outrun a bicycle.
