You may not be recalling correctly. 08-09 The NHSTA data I can find shows no sub 1.0 death per million miles.
They show 1.26 and 1.15 death per million miles - both worse than Tesla Number.
The lowest they show (that I can find is) 1.08 per 100M miles I can only find to 2014.

At 1.0 per 130M Tesla autopilot is markedly better with less fatalities and one third more miles.
Good commercial Shannow.
