Every time i ride in my gf model s i often get headaches.She drives pretty conservative but when she accelerates its a strange feeling of g force compared to my sports car. I cant really explain it. Maybe its the outgassing new car smell? But it feels strange. I also wonder since its all battery and its a d model and wifi enabled if there is any rf issue to health?? Like all the wi-fi in the car and the batteries you sit on all the time? Just curious. I can tell its an electric motor acceleration type from front and rear from the way it takes off but for me it still feels odd and somewhat nauseous. Or least t makes me feel this way when driving in the car.
