What keeps me going with this blog and the promotion of Not So Fast? Emails like this one, from a mother of a new teen driver:

“I just finished “Not So Fast” and printed out the Model Teen Driving Agreement. Last month, my son flipped our vehicle on a slippery road while buckled in and not speeding (going the speed limit of 35). He had his license one week to the day. He had his friend in the car. Their guardian angels were with them and they are OK. We had signed the Allstate Teen Agreement but I like yours better. We are updating our agreement and we are far more knowledgeable after reading your book. I’m so sorry for your loss. Reid was a beautiful young man.”
