With more Tesla sales, the more Tesla sells, however, so I hope they'll place a service center closer to your abode. (And there's always mobile service as well.)
Second, I think Powerwall 3 will be a game changer and allow for more cost efficient solar installations, which will be key to increase adoption.
Lastly, as for "never" payback periods: for some, it WILL COST MORE to transition to a no-carbon future. Is it too much to ask for those that live in low-solar climates to pay a little extra to stop dumping their GHG's on future generations?
I hate to be blunt, but sometimes (often?) doing the right thing isn't easy, but it MUST still be done. I know we stretched to buy our first Tesla back of 2013, and it was a huge risk as dozens and dozens of car companies have failed over the years, but we spent the money because it was the right thing to do . . . .
My earnest hope is that this sort of thinking, and the joke that is COP26, is what is driving Tesla's massive (and growing) order backlog. People are waking up and realizing that The Problem isn't going to be solved by global "leaders." It's going to be solved by US, personally, not buying fossil fuels, one person at a time.
