In the next couple days I take delivery of a 2017 FSD 60D to replace the 2016 70D stolen from me by my family members. God help me. This is the emotional validation post I make fun of when others do it. Does anyone feel as I do? Fixated on free supercharging? There are STILL new cars popping up every other day or so in inventory which have it all: Lifetime supercharging + 2017 model year Post-Jan 23 build dates (small overlap crash protection improvement - hopefully no more concussions on dummies) Ventilated seats Air suspension I can't stop looking at them. I have the urge to collect them and put them in a warehouse for safe keeping and a hedge against an imagined electricity-price-apocalypse. WTF is wrong with me? I shouldn't care. The supercharging - under best possible case scenario ($20,000+ free electricity over 10 years) is financially irrelevant to my life compared with the time savings of a 100D vs a 90D (no 100D's have unlimited supercharging) over the same 10 years. But I can't stop thinking of anything money related in terms of NPV of future discounted cash flows. And I can't stop seeing these last few S's as some magical "self driving, unlimited fuel-for-the-rest-of-Calisnow's-hopefully-long-life" space ship. Which is ludicrous - because as soon as Elon drops a car with lidar on us and a 5 minute charge time - I'll dump my free supercharging car and buy it. But in addition to my love affair with cash flow I have an aversion to depreciation. So instead of buying myself a 100D (which I really need right now) - I've sprung for: a 60D with FSD and air springs. Next winter in Wisconsin in -15F February I will creep along in my 2017 60D at 55 mph, shivering in electrically heated socks and gloves, a thick hat and a blanket so that I can make it from one work location to another without running out of juice. I will photograph myself freezing my ____ off with icicles dripping down my nose - and you will laugh at me. But GODDAMNIT I won't be suffering the depreciation hit of a 100D when I compulsively upgrade to whatever Elon has in store for 2019. I'm insane.
