But AustinEV: in the a-bit-more-distant future the following will likely happen:
1) Tesla will sell substantially more cars every year than they have done so far
2) the SC network gets "fully built out" at least in
places like the US and Western Europe
3) Electricity will be relatively speaking cheaper than it is today, especially when generated on-site with solar or off-set by solar someplace else.
1+2 means a lot less $$$ per car going towards investments in further expansion
3 means the money claimed as pre-payment covers even more kWh.
With this in mind $2000 per vehicle, or thereabouts, looks like a pretty sweet deal for Tesla but is at the same time still a good value proposition for the customer.
Also, these cars won't "live for ever" and for large taxi fleets just look at Schipol Airport: they have their own charging set up. I don't know the details but I believe it's a bunch of 22kW AC charging. There is no public SC there. I don't believe they have a SC and if they do I'm sure it's financed and being run separately from the general SC network. I believe there are some terms in the purchase agreement that states that "free for life Supercharging (prepaid)" is in fact limited to personal use (not commercial use) but don't hold me to this statement.
I will try to extract myself from this, but you are doing a great job of explaining why the current model of financing it is probably fine, which I agree with. My beef is that it takes a complex analysis to explain it to people. I dislike the financial complexity. I am not afraid that TM will go bankrupt over it, I am afraid that Mr. Market applies an unnecessary discount to the stock value because of indeterminate commitments like this.
Actually when I explain the SC network, i don't say its free. I say its free, then they look at me like I am crazy, then I say "well its more prepaid. There is like $2000 built into the price of the car that is for electricity. Since each charge is about $5 it is virtually impossible to spend that much so it works". So, that is a needlessly complicated message. I could just say don't worry about it its magic, but that is worse; people can't just accept something for nothing, they want to pull at the threads to find the scam.
I am probably in the minority in thinking of the liability and losing sleep over it. Y'all are sleeping well and don't understand and that is perfectly fine
