I'm currently down in Oregon in search of wind and/or surf and have been logging many hours in a somewhat turtle-ey position while driving large distances in my car (yes, I feel some shame for a Mordor-sized carbon footprint). Being a lanky type of person, I sometimes struggle to sit upright in most vehicles without scrubbing my head into the headliner with my face cocked to the side like a driving wraith or zombie. For me driving position ends up being a series of compromises, and I simply resign myself to "undoing" the postural damage later.
