Honestly, I would expect the NTSB to investigate any kind of accident involving rare or new technology. I'd expect to see them investigate a higher percentage of accidents involving electric vehicles and self-driving vehicles until those technologies are safe enough and proven enough that you get diminishing returns from the investigations.

Tesla probably also has one of the higher counts of deployed electric vehicles out there too, so the absolute number of units involved in anything unusual should be expected to be high too. The interesting context would be relative numbers to number of units and miles travelled for both regular vehicles as well as other makers electrics.
