The website states very clearly, in bold, at the very top:
> Tesla Deaths is a record of Tesla accidents that involved a driver, occupant, cyclist, motorcyclist, or pedestrian death, whether or not the Tesla or its driver were at fault
The FAQ contains the reasoning behind that, which is very simple:
> Q: Why do you include deaths where the Tesla was not at fault?
> NHTSA death statistics cited by Elon Musk do not differentiate between at-fault and not-at-fault. All manufacturers are treated the same way. For the purposes of calculating Tesla fatalities in accordance with NHTSA methodology, we also do not include the many deaths in other vehicles, despite Teslas being at fault in the majority of those cases.
Note that since this is only based on press reports, this is a lower bound on the number of deaths. Probably by a signinficant margin.
