Interesting, thanks - I was going by the combination of what I can see on TeslaFi (ie overall vs cars like mine), plus anecdotally in the various “stuck on old firmware” threads in the different forums on here, then also what Tesla-Info shows (which has a differently-sliced breakdown, and I don’t know what their data sources are, sorry):
Tesla Release 2023.2 statistics and heat map
Would be fascinating to find out what the reason for holdback of any updates to that fair subset of cars for 2 months is, but it seems deliberate rather than just the usual roll-of-the-dice on when some particular car might get an update.
