The plot thickens there in Figure 3 where they suggest mistreatment of deployments/miles that occur between `Prev Mileage before Autosteer Install Reported` and `Next Mileage after Autosteer Install Reported` "result in estimates of the true exposure that are statistically biased downward – resulting in crash rates that are somewhat too large." [pg.13]
And then, Figure 4, 15 deployments are counted before instillation while no additional mileage is counted for the before instillation group. [pg.16] Could the NHTSA group really have done that? It give us an incredible rate of 15/0 deployments/mi without autosteer which violates some very important law of arithmetic, statistics and common sense.
I'm going to hold my breath until we see the data these claims are based on.
