Actually nothing. No doubt they have the absolute latest tech, its also hugely untested, unreliable and they spend millions hiding the accidents that happen
They sell a million of those things a year and pipe real time data back home.
Compared to Johnny Startup who's got one mockup in a lab that's a LOT of testing. Accidents are testing. How many wind turbine startups have 1 million data gathering units in the field in comparison.
My point is victorious lilli.
