From tables 1 and 2, about noncrash fire losses / insurance claims from cars built in 2016-2018 if I'm skimming this right: IVY RFC Make and series 36k 192 Tesla Model X 4dr electric 4WD 43k 140 Tesla Model S 4dr electric 4WD 50k 288 Dodge Charger HEMI 508k 101 Ford Fusion 151k 49 Honda Fit 21k 0 Chevrolet Sonic RFC = Relative claim frequency which has an asterisk in the document saying "100 = all-passenger-vehicle result". If 100 is all passenger vehicles... result? I can't parse this sentence, but I take it to mean that 100 is the average of all cars. IVY = Insured Vehicle Years, basically sample size Given that a car with 21k exposure years can have 0 claims, and there are also combustion vehicles with higher values, I'm not sure how statistically significant it is that these Tesla values are >100.
