Of course sitting to much isn’t good, but some things happen. I have a 90 mile RT driving commute that fortunately is mostly open Interstate so it takes about 90 minutes a day total. I currently dirve a Honda Civic coupe with a sunroof and I’m 6’2″ and 200 pounds. The roofline and console pretty much keep me in the same position, somewhat leaning back for headroom and reaching out a bit for the steering wheel. The console and the small, narrow car in general keep me from using multipe postions for my legs.
As I may be in the market for something different in the near future, was looking for suggestions, article links, about vehicles that are good to your body.
