Or people will put off buying new ones and keep old ones longer. Used prices might rise, increased spare part and servicing costs/income for a while, but eventually Cybertruck & others will be the shiny aspirational things. Buying second best will seem naff.
I mean- that certainly doesn't happen with ICE vehicles.
Some ICE trucks are clearly better than others, even at the same price point- but ultimately there's a bunch of them out there and all them get some sales.
No reason to think that won't be true of EVs as well.
You can Osborne yourself and Osborne others. My guess is that during the transition from horses to ICE, new horse-carriage sales dived a long time before cars were produced in overwhelming numbers.
I'd actually be really really curious to know if that was the case.
Because in most places the transition wasn't actually nearly as fast as people seem to think it was.... (a lot of folks try and use NYC as an example, which got to "majority" cars fairly quick- but is unlike 99% of the rest of the country- and still had a surprisingly high number of horses in service into the 1930s when you look at the real numbers- and most places with less density too even longer to get off horses)
Remember, even Elons own, most optimistic, projection is MAYBE there'll be 30 million new EVs a year by 2030 (with maybe 20 million of those being Tesla)
That's still less than
half the # of new car sales annually today.
Tesla's doing a lot to scale up batteries to hit what is a very aggressive target, and it's still not gonna be the majority of the market 10 years from now even if they hit ALL their goals.
ICE cars suck, but they're still gonna be built and sold new for at least another generation IF Tesla executes their plans perfectly, because battery supply really is that limited (plus energy grid concerns in a lot of 3rd world type places but that's a whole other discussion).
What is kept secret? Elon have been talking about this release to internal people for two months now.
Probably just how beta it may or may not be.
Remember Elon said the re-write would do things at launch that it wouldn't do WELL for at least another year from now.
Enhanced summon was in highly limited early release for about
a full year before they decided it was safe enough to let everyone have it.
I don't expect that here- as I imagine initially it'll mostly just be replicating features the old code already did but doing them better, rather than adding tons of NEW stuff.... that'd come later as more testing/improvement happens with each feature- but if the initial small limited beta DOES find an existing feature with a problem they'd probably prefer to find out and fix it quietly than chance some TSLAQ folks getting wind and pushing a "NEW REWRITE IS WORSE IT IS AP1->2 ALL OVER AGAIN" type narrative.
