I have a sensitive back and feet issue. In any case, I rented a Model 3 for a few days and holy hell my lower back is absolutely killing me. I moved the lumbar support around a bit to no avail. I have driven a Chrysler 300, a 1994 Cadillac Deville, and rent Toyotas and Nissans all the time with no issue. These Tesla seats have my back all jacked up. Has anyone else had this issue? I love the car but this will be a deal breaker for me. I was driving on and off for 3 hours today and I need a deep tissue massage with this back pain. It's from the bottom of my shoulders down to my far lower back. Im 200lbs and 6'1". I feel like you do when you fly coach on a 5+ hour flight. I did have the same issue with the new Cadillac STS and the smaller Benz.
