I'm sure there are alternatives, but If you spend a significant amount of time in your vehicle everyday, the size and comfort of the vehicle does come into play. For one, if you are a big person, either horizontally or vertically, a Prius can become less than comfortable. Also, sciatica and back issues can come into play. I know for me, sitting for too long in a small car keeps me folded a little too tightly to the point that my lower back will start to throb. Where sitting up and stretched out with a high enough seat to keep the bottoms of my thighs supported while feet are flat on the floor or at the petals makes a big difference for back and leg pain.
