...so we "theatre danced" (the same as car dancing except in a theatre. And you can do line theatre dances too if you have multiple people). Do my suggestion with you is go with dance friends, and make it a fun outing!
I was in belly dance tonight and we were working on rib isolations (moving your ribs up/down, forward/back, left/right) and stomach rolls (where you tighten and release the three seperate areas of muscles in your stomach to make your stomach roll up or down), and our instructor said the best way to practice each of these techniques is in the car (or sitting on the edge of a chair or sitting on the floor).
Essentially, when your sitting (like in the car) your hips and pelvis stay isolated automatically so it is easier to move only your ribs or to isolate your stomach muscles.
I literally almost burst into a fit of giggles when she said this as I do rib isoluations ALL THE TIME in my car as I'm driving to an from places...and I couldn't stop thinking about this thread!
Car Dance! I sometimes drive 10-12 hours a day -- car dance is my survival mode, nearly the only way I can practice -- and you'd be surprised what you can do with cruise control on, good music, a mostly empty highway, and a lot of visualization... Not to mention what happens when some how-can-you-sit-still music comes on when I'm just plain running errands around home...
I see a little silhouetto of a man
Scaramouch, Scaramouch, will you do the Fandango
Thunderbolt and lightning, very, very frightening me

I'm just a poor boy nobody loves me
He's just a poor boy from a poor family
Spare him his life from this monstrosity
