They have a different business model than OEMs, this is not apples-to-apples. OEMs act as wholesalers.
Besides the fact that you're talking about the efficiency of a company that literally produces 10x the number of cars. Let's see what happens to Tesla if they ever reach that scale.
>Toyota: 2.6M (+5% y/y) Tesla: 344K (+42% y/y)
Base rate fallacy. Why not use absolute numbers of cars, rather than percentage increase? It would tell a different story, wouldn't it?
10x higher production should in itself bring a lot in terms of economies of scale. Generally, the more you make of something, the cheaper one unit is to make.
So Tesla's position is certainly more impressive in this comparison.
I'm not even saying they don't have great manufacturing practices objectively - if you compare them to a lot of other industries they absolutely do. But auto manufacturing has always been the cutting edge of manufacturing tech and they simply are not at the top of that highly competitive field yet.
I'm curious, because sometimes exceptional supplier expectations come from a customer not really knowing what they need, so they ask for the world.
In doing something as simple as making their own seats, they were able to also improve the safety. They've put sensors directly in the seats to reprogram airbag deploy sequences, in software, on the fly. They know if there is a child sitting on the very edge of the seat vs an adult laying down across the seat and have the airbags fire differently based on this knowledge. Recently[2], they stepped this up a notch and are in the process of using millimeter wave radars to confirm this. They're industry leading in this regard and previously just used pressure sensors plus the cabin camera above the rearview mirror.
In short, Tesla is not perfect, but they are trying to rethink the problems from first principals. In doing this, they are coming up with very novel approaches that are actually big improvements over the entire industry. In other areas (fit and finish) they're towards the middle of the pack when compared against peer auto manufacturers.

For comparison, if Toyota was as efficient as Tesla they would've posted 2022 Q3 profits of ~$24 billion, not $3.1B. Tesla achieved $3.9B from only 344k cars. Operational efficiency is their leverage.
Cars sold (2022 Q3)
Toyota: 2.6M (+5% y/y) Tesla: 344K (+42% y/y)
Operating profit excl. FX impact Toyota: $3.1B (-38% y/y) Tesla: $3.9B (+97% y/y)
