Your comment about him getting anxious when you stepped on the brake is interesting. Our baby loves to go for a ride in the car and loves to bark at anything she sees while riding. She also will sit on my lap and sleep an entire trip if we are on an interstate. However, as soon as the brake is touched, she has to sit up and look out. She doesn't get nervous, but she has to see what is happening. She can be completely out, but that brake goes on, even slightly, and she is up and looking out the window.
