I'm still amazed that they actually use 18650's.
They used them early on because they were so readily available. Thing is when you design a car around a particular battery-pack form-factor, it becomes somewhat difficult to change.

I just would've thought they'd scale something similar to an 18650 to a larger form.
They did. The packs in the Model 3 use 21700 cells. Tesla had a lot to do with that becoming a standard size.

Maybe when they have all the new super efficient tech ready for market (1 min. charging, silica instead of graphite, "air" charging with rf), something the size of a AAA will replace our 18650 models, and we can just use a sleeve like the 21700/18650 ones available now. But you probably won't be able to charge on-board anymore.
I'm not that optimistic about quantum leaps in battery tech. People keep publishing papers with claims that they've come up with some big improvement, but we've yet to see any of them make it to mass production.
