I doubt vehicles will ever be made to last that long even if possible. Especially as newer types of cars (EVs) have less maintenance costs the dealers are really going to need to push people into buying a new car every X number of years, which I imagine theyll do with planned obsolescence like all the electronics manufacturers do.

They are already doing it now, if your battery is done for they just say oh well buy a new battery for 10K or a new car lol
