This is a popular Japanese car model. The head rest tilts forward, making it impossible for her to maintain a neutral spine. Notice the rounded shoulders and forward head position. This puts strain on the muscles just under her head, in the lower neck, and across the shoulders.
Most people recline the seat back to keep the head rest from pushing their head forward. This now causes her to reach for the steering wheel, rounding the shoulders even more. It also causes her neck muscles to constantly fire to hold her head up to see the road, and increases the distance her head will travel in an accident.
Here she is using the Travel Buddy to fill the space behind her shoulder blades. Look at how well her head and shoulders are aligned with her spine. This decreases the workload on the neck, shoulder, and upper back muscles. She is also reinforcing good postural positioning for when she sits and stands the rest of the day.
