Thanks for the ideas and answers. I ended up buying a 2010 Odyssey. Of all the vehichles I've seen, it had more horizontal leg room with nothing to intefere with sliding the right leg outward, toward center. The Toyota Sienna was pretty good, but it had some sort of floor tray with a lip which prevented quick, easy sliding of the leg back and forth. For long road trips, using cruise control, it's nice to have this capability, especially if your prone to leg and hip discomfort.
BUT, the Odyssey is a gas hound in town, so I was looking around.
Interesting that most all cars nowdays have this cockpit-type driver's compartment which is created by the console on the right side.
