My argument is more than cogent, it's valid. But given you've failed to address them or the evidence, your critique's useless, invalid and totally unpersuasive.
Now onto your arguments: at their core they amount to A: "my car doesn't have the problem, so therefore no other car from the same manufacturer can have the problem either" and B: "previous versions of iOS have had BT issues (which you proclaim without any supporting empirical evidence were the fault of the auto manufacturers), so therefore it's the fault of auto manufacturer's that iOS 8 is now having bluetooth connectivity issues" -- both of which have numerous fundamental fails of basic logic which render them invalid. By the way, you might see if a Texas university near you offers a class in basic logic in order to strengthen your skills in basic argument. The latter is so flawed I could write many pages about your failures of basic logic and supporting evidence. But in the interest of brevity, I'll just rip the former to shreds: Your single error-free outcome with your particular equipment doesn't render invalid the countless problematic outcomes being reported with similar or different equipment. Similarly, if you had smoked cigarettes for decades without developing lymphoma, your single, particular cancer-free outcome doesn't render invalid the empirical causal connection between cigarette smoking and the lymphomas presented in hundreds of thousands of people who also smoked for years. That's why scientists use EMPIRICAL, PEER-REVIEWED evidence to draw conclusions and not "a single outcome of some self-proclaimed (from your profile) former cop turned slacker."
Contrary to your pathetic attempt at invoking the common defense of ad hominem attack, I actually didn't call you names at all. Actually I made an observation about your behavior (a behavior which is called trolling) -- and given that you trolled another user on this thread, and you're tolling me now, it's a correct observation supported by the evidence.
As for your statement "Apple adheres to all current BT standards as does the manufacturer of the chipset maker that they buy from" -- how can you make this statement authoritatively? Are you the Apple, Inc. programmer who programmed the BT software and firmware in iOS 8.x and Apple Watch OS 1.X? Are you the procurement officer who procured the BT hardware in the iPhones and Apple Watch raised in this thread? To which exact BT standards are you opining? All of them? To which versions of iOS are you opining? All of them? To which exact chipsets are you opining? All of them? To which exact chipset manufacturers are you opining? All of them? To which chipset firmware versions are you opining? All of them? Etc, etc, etc...
Recommendation: Go troll someone else, you are persuading nobody.
