R2 production through 9/24 is about 10.6k, 2k below the 12.6k highest assigned VIN
Rivian assigns VINs in color batches, so serials run out of build order
For example, this photo from
@RivianTrackr's factory tour shows serials 3,533 and 5,204 on the line at the same time, and September builds show the same pattern
