We have had a few things we noticed that could cause it. Both my wife and I notice our windshield has areas that distort our vision way more than any other car we have driven. We have also noticed this in our rear window. I don't know if it is the big angle the window is in at or if it is the glass, but everything is distorted out our back window. The comments on regen are accurate also. One of our big ones that went away shortly after getting the car is the lack of noise and how your brain has to adapt. Our brains are so used to feeling acceleration at the same time as hearing the engine. This was something that took a few days to get used to for us.
