I was going on I-95 North (Palm Beach County) on Autopilot (and I had Full Self Driving enabled in my car). It was raining, and I was at moderate speed, I would say 45-50 mph. The car started spinning uncontrollably. By miracle nodoby hit me, the card corrected after what I believe were 2 spins and continue on the same direction as traffic. I believe, with the nerves of the moment, that about 45 to 60 seconds later, I put auto pilot again, not knowing what hapened. And the car, out of nothing, started spininng again. 3 times, and I hit the opposite wall of the highway. By another miracle, nobody hit me (rush hour, I-95 north, 820am)
