Was cruising along the i-90 tunnel in Seattle, WA on mercer island with my wife and 2 kids, when I hear some vehicles approach at high speed from behind. Then suddenly I hear a screeching sound from a car breaking hard, and then a car slams into my rear end - hard. I was going 65, so that vehicle must have been going significantly faster. From there I lose control of the car, and the car spins out of control, hitting the freeway divider wall all the way on the other side of the freeway 4 lanes across, and then bouncing back all the way back to the other side of the freeway and hitting that wall before coming to a stop. Thankfully the model 3 performed miraculously, crumple zones compressed, airbags deployed, no fire after the accident, and no one in my family seems to be seriously injured. Still processing what just happened and getting all the facts from the police (there may be a criminal case against the person who hit me), but any tips and things to watch out for as I go through the insurance process?
