FelixDeCat: rather than this unfounded theory that because other people driving EVs somehow drives up your insurance rates theory I would suggest your real problem is owning a car that has high insurance rates because of excessively high theft rates provenly caused by a manufacturer's design flaw. It is precisely because of the car you own (Hyundai Tuscon) that your rates are high. It is quite likely you didn't know of that problem when you bought the car but it is an unfortunate fact that can't be ignored.
On the off chance you don't know about this theft issue (it's been in the news a lot) I strongly suggest you google it immediately. You may also want to research whether shutting off the Blue Link services increases your risk of theft and/or gives the manufacturer an out for any liability for the theft of your car. I don't know if it does but I can see that problem arising.
What others said above about monthly service charges always (or nearly always) being the most expensive route is certainly true in my experience and I always check the effects of various bill payment strategies every bill I have. Over the years I have never personally encountered an insurer that didn't tack on service fees for monthly installments (they almost always have extra fees for anything short of PIF for the full policy term).
Please don't take this the wrong way but I think if you focused a bit more on your critical thinking skills and implementation thereof your life would be cheaper and more stress free.
