In brief: Muscle fatigue

Muscle fatigue from continued activation of the same muscles over a period of time.
This can lead to overcompensation by the surrounding muscles and worsen your discomfort and cause prolonged muscle tightness and spasms. Getting out of the car periodically may help to prevent this or some additional lumbar support on the car seat may help as well.
