Road Rage or Motion Withdrawal
I noticed in the car when driving with Madeline that she tends to get tired when the car is in motion. This isn't news to anyone that kids get sleepy when you are driving. Some people with babies who can't sleep will drive in circles through suburban streets to quiet their babies. Very young people aren't unique in this inability to maintain consciousness while in a moving vehicle. Leelin the pug dog and countless other dogs uncontrollably nap once the car is in motion only to awake at the park where we are going for a walk.
So this has led me to a theory about Sarah's road rage. Sarah has terrible road rage to the point where she turns into a raving lunatic every time there is traffic that she is stuck in. Well the converse of the sleepiness happens for the babies and dogs as well. When the car stops the baby wakes up, and the pug dogs struggles to make sure he isn't left behind. The alertness of a stopped mammal in a vehicle is at the level of anxiety regardless of whether they are in a hurry or not. Dogs and babies have no real concept of time or traffic, only stopped or moving. So Sarah and countless other drivers may sufffer from what I'll consider to be motion withdrawal. When a car they are driving or riding in stops they get a sudden anxiety attack from the removal of whatever internal brain chemistry passifies them when the vehicle is moving. This is a tough problem to combat because it is a side effect of driving and you can't simulate the magical moving process while you are in traffic. But it does explain why people, including Sarah, me, and my dad will go to extreme lengths to drive a back route that may even be slower to make sure that we are moving the whole time. Maybe a GPS system could help with this. Just keep the driver moving so they don't turn green and rent their clothes as they transform into the incredible hulk while reading the pro-life bumper stickers of the car in front of them.
