I pay for it because I'm pretty much desensitised to the whole SaaS death-by-a-thousand-cuts model of about a hundred seemingly-not-too-bad-in-isolation monthly deductions coming out of my account every month.
If someone asked if would I pay £120 a year for premium connectivity I'd probably say no, but somehow £9.99 a month doesn't seem so bad? I guess that's why they do it.
Its funny you say that, lol.
To answer the thread question, I also pay for it monthly, but every month I see the charge I hate it. Its not because I dont think premium connectivity has $9.99 worth of value, for me it does. Its because I hate (hhhhhhhhhhhhhhhhhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaatttttttttttttttttttttttteeeeeeeeeeeeeeeeeeeeeee) the SaaS model of "100 seemingly not bad in isolation monthly charges" (as you so aptly put it).
I personally would MUCH rather pay $120 a year, than $9.99 a month, and pay yearly for these things whenever I can. That makes me decide "do I want this thing for a year for $120?" I also really dislike monthly bills. I have my home mortgage and my cars as monthly payments, but other than that and utilities (gas, water, electricity) I dont have many other monthly bills unless its something like this where I want it and have no other choice.
Its easier for me to wrap my head around value to me (or not) at the yearly price, and I dont get "annoyed" seeing it hit my credit card monthly. In the case of premium connectivity, I like it enough to tolerate paying for it monthly. I have read stories of people contacting tesla to get it billed yearly, but "Tesla being Tesla" and that being "not a regular option" I dont trust them to actually do that correctly.
Probably sounds like I am hating on Tesla with that statement and I am not, I have A model 3, Tesla solar on my roof, and Tesla powerwalls in my garage. I am just a realist when it comes to certain things and one thing Tesla as a company does NOT do well in any way, shape or form is "lets do this thing thats outside the norm of what we offer standard".
Since they dont offer a yearly price for premium connectivity "standard, in the app or website" and you would have to call someone to set it up, to me, that would have a 50/50 chance of either not working, or not ever being able to be canceled should one change their mind "later"... so I suck it up and pay monthly.
/e climbs down off soapbox now...
