I have an S with the Napa leather seats which I really like. I drove a P3 today and the white seats are terrible. The material is too soft for the foam and there are no bolsters of any practical mention. The white is also softer than the black interiors. These seats disconnect you from the driving experience and have no place on the P version or any 3 for that matter. Seems Tesla is catering to overweight Americans that like Lazy Boy seats in their Tesla. I find it odd to drive a car with stiff suspension and great handling but seats that are like marshmallows. I know they dumbed down the seats as they were nicer than the S seats in prototypes but do they have to be so bouncy and lack any side support unless you are 250 lbs and your body pins you to the doors? I was interested in the white but there is no way I would order these and I'm on the fence about the black seats. Try both side by side in two NEW cars and see what you think. After the drive My S seats felt like after market racing seats.
