I'm doing some research on the safety of the rear facing jump seats that Tesla offers in their Model S and came across your work - well done. Surprisingly, I'm having a very, very difficult time finding any supporting data on the safety of the rear facing seat (jump seats). It doesn't appear that Tesla nor any government car safety organizations have published any regarding the safety of the seats. Elon Musk says they are the safest seats in the car for front and side impact, and they have added a double octagonal crash structure in the rear (). Though I love Elon and my Model S, I'm looking for a bit more reassurance from a data perspective. After two recent rear-ended accidents (We Talked To The Tesla Model S Driver Rear-Ended By A 40-Ton Semi and Rare fatal accident in a Tesla Model S rear-ended by a large SUV in California), I'm having my doubts. It appears that if the colliding vehicle sits higher than the Model S, it's reinforced bumper does not aid against the ingress of the hatchback. Any concrete data, research, or commentary from a professional in the industry would be most appreciated. Thanks.
