"Our data shows..."
Note the use of the keyword data. This appears frequently in Tesla statements. It implies certainty and technical understanding.
"...that, when used properly by an attentive driver who is prepared to take control at all times..."
Interesting condition.
"...drivers supported by Autopilot are safer than those operating without assistance"
This is garbage logic. It's just saying any errors that aren't corrected by the driver are cases of "not using it properly." Of course the "data" will show improved safety if you exclude all the accidents.
