My wife is getting a 2010 Prius 4 Solar Sunroof/Navigation in a few weeks. I am 6'6" and will ride in the passenger seat about half the time and be the driver about half the time in her new Prius. I've sat in the Prius and been on a short test drive. The telescoping/ adjustable steering wheel enables me to sit OK in the car and the lumbar support on the drivers seat seems to add some support. My question is will I be comfortable in the car on longer drives (particularly as a passenger without the lumbar support?) My reference point for comfortable seats is my wifes' current car, an Infiniti FX35, and my Infiniti M35.
