The fatality rate of an accident includes all parties involved. Most often when a Tesla hits someone, it kills the other guy, since it's basically an ultra-dense block of mass that can do 0 to 60 in 3.5 seconds, very quietly and without launch control[1]. Teslas are incredibly safe for the people inside the Tesla.

[1]Lots of other cars have technically faster times than Teslas, but most of them require launch control, good tires, and sound like the engine's about to explode. You can floor the Tesla at any time and the software will deliver however much power it can without slipping.
