Statistically insignificant. Tesla stats will only matter when tens of thousands, if not millions, of trips have been made under autopilot.
The problem with waiting around for better data is that you're asking consumers to be the guinea pigs for an untested and potentially dangerous device. Through their overreaching marketing, and their lack of transparency, most would not trust Tesla with their life, and those that do, do so at their peril. A safer (albeit slower) approach would be for Tesla to demonstrate safety through public testing data.
