We just returned from a 61/2 hour trip and we were very comfortable. I am 6'2" with bad knees. Every other car that I have used for this trip caused my knees to be stiff when getting out of the car after a few hours. Not the Prius!Russell Roberson said:Any way to make the Prius driver's seat more comfortable for a long trip?? We're going to be driving 8 hours in one day and would like some help!
