Something you may not have thought of.
I recently took a project with me to hand stitch in the car (needle turn applique). The bumps and turns made it difficult, but not impossible - but worse than that was the fact that I was getting car sick! I never - ever - get car sick. But the act of looking at something stationary while moving made me car sick - even though I was looking up every now and then (usually to see if there were any more pot-holes that my husband could find on purpose!).
So you might want to try taking a small project on a road trip with you to see if you like stitching while driving.
