The Lexus GS Fsport with rear steering has the tightest turning radius of any 4-door sedan I have driven. I also had a 5 Msport and we also have a 3 series. The Tesla turn radius feels similar to a BMW 5, not as good as a BMW 3. The Lexus GS Fsport felt significantly better than even the smaller 3 series. On any 2 lane road, the car could complete a U-turn without any steering towards the other direction, or use any shoulders... I think you need like a small Porsche to turn tighter than a GS Fsport.
