The often quoted typical lifespan of a single 18650 cell is 300-500 full cyles. How does Tesla get their car batteries, wich are essencially 18650 cells, so far above that? Some sites claim 2-3k full cycles. I want those 18650's!

a life cycle of a single cell would be about 300-400 cycles now when you make that cell both in parallel with others and series with some others you in crease both its overall capacity but you also share the charge/ discharge cycle Telsa claims it to have a million mile battery but still suggest a full replacement every 5 years if i recall correctly.
also take into account how they are charged. at a much higher amperage with lower voltage i suspect
also please consider that this new tesla battery maybe a exclusive to tesla and that it may not have the standard safety feature or chemistry for a consumer battery for are vape use. it could even be marketing hype but if true one day it could possibly make into consumer 18650's but that is most like 5-20 years away unless your elon musk and make it sooner. https://electrek.co/2019/09/07/tesla-battery-cell-last-1-million-miles-robot-taxis/

you can read up https://electrek.co/2019/09/07/tesla-battery-cell-last-1-million-miles-robot-taxis/
they cover just about the whole topic
A tesla battery sled holds over 7,000 batteries.
Even if they were as cheap as $3, nobody's gonna do that. Plus I think you have to remove the entire body from the sled to get to em.

thats why the batterys come with 8 year warranty from the factory
actually swapping the thing does not take long https://www.tesla.com/videos/battery-swap-event
Oh I see... the sled is replaced as a unit. I somehow had it pictured
snapping seven thousand batteries back into the original sled.
Cool video. So how much for the replacement battery module?
