Whoa! That makes the non-AP Teslas look really bad! Let's say, X is non-AP Tesla claim rate, Y is comparable cars' claim rate. Let's also say, 50% of 2014-2016 Model S were AP in the study.
So, we have: For Model S : (X + 0.6X)/2 = 1.46Y => X = 1.825Y => pre-AP Model S was 82% more accident prone
For Model X (only AP cars): 0.6X = 1.41Y => X = 2.35Y => 135% more accident prone, IF Model X didn't have AP.
Either something is wrong with this 40% claim, or these pre-AP cars had very bad accident rate (terrible drivers, terrible cars or both). Or the AAA data has some flaw (least likely, imho).
You replied to my statement with 2 parts: claim rate and insurance cost. Yes, the presumed rich current Tesla buyers may not care about insurance costs. But they usually care more about safety; i.e. claim/accident rate.
Not even close. You are trying too hard to spin things into a negative as much as possible.
Here's the two relevant quotes:
"Figure 11 shows the rates calculated by ODI [Office of Defects Investigations] for airbag deployment crashes in the subject Tesla vehicles before and after Autosteer installation. The data show that the Tesla vehicles crash rate dropped by almost 40 percent after Autosteer installation."
"Model X file for claims 41 percent more often than average, and those claims cost 89 percent more than average, according to the institute."
1) The 40% figure only counts
airbag deployment crashes. Obviously many crashes/accidents do not involve airbag deployment.
2) The insurance figures only count
claims, not the amount of
accidents. There are plenty of accidents where claims are not filed because they are under the deductible, sufficiently close, or the owner didn't have collision coverage for their own car.
There's a couple of factors that could increase claim rate independently from accident rate. For example, high repair costs would raise a similar accident to over the deductible, while another car might still be under. Also, being a premium car, with many being quite new, it is less likely for the owner to go the cheap route out of pocket. Being a niche car with less available shops also reduces the possibility of going cheap.
