How is that not the definition of biased in the context that I used it. Owners are biased of Tesla's reliability because it's offering them something that they can't get elsewhere. In your example, greener emissions and lower overall expenditures in a pure EV. That is the exact definition of biased. But you're using the word biased and applying a negative connotation. I don't feel that just because people are looking over issues that they normally would not some how makes that bad. It just gives abnormal results, just like that second article posted implies...paradox.
In regards to the 5 competitors being at the top of the charts and Tesla not losing ground, I thought the first part was implied? Obviously if Tesla is doing this well now in satisfaction, then 5 like competitors aren't going to drop it to the bottom of the ICE list. It would drop it to the bottom of the like competitor list. Which I absolutely 100% feel would happen assuming Tesla was stagnate in addressing quality issues. They aren't but it's a hypothetical what if anyway. Once people have like choices then they'll be much pickier.
It may well fit
your definition of the word "bias" but it has nothing to do with any dictionary definition or other real world use of that word I've heard. When somebody likes something because of one or more real properties of that thing which are of legitimate value, that isn't bias. Bias isn't based on reason. It's based on emotion. It's liking the image of something or the mere
idea of it, but having little to do with the reality of it. Or being partisan like AMD v. Intel and always only buying one brand regardless of which one is better in the current generation.
If I like to have plenty of cargo space and I like a car because it has plenty of cargo space, that is not "bias." Similarly, if I hate paying high gas prices and I like a car because it requires no gas, that is not bias either. Nor is it bias to prefer one gas powered car over another because of better gas mileage.
For that statement to hold true....you would need to provide examples of other brands with very high satisfaction ratings but low reliability ratings. Perhaps they exist? Maybe Range Rover? And like I already mentioned, the Model 3 is noted to have much better reliability than previous models but the satisfaction ratings were very high BEFORE this model was released and related to the prior models.
In the end it doesn't matter that much as Tesla will have fixed most of their major issues well before there are even 2 like competitors on the market let alone half a dozen.
I don't research car satisfaction rates except every 7 or so years when I buy a new vehicle, so I can't answer that question. What I do know is that owners of Teslas in surveys, and numerous people I know (at least a quarter my friends own Teslas - no kidding!) cite a mixture of factors inherent to EV's (avoiding high gas costs and environmental friendliness) and factors not related to EV's (smooth ride, great handling, good comfort, advanced features) as why they like their car.
