Sorry if you misinterpreted my view. Having the Telsa OTA update function is a great benefit to the consumer just as it's
beneficial for other consumer products, e.g. PCs & cell phones. But just like with those products, there're limitations over
time (as systems evolve), e.g. a minimum required processor/memory, faster USB ports, 4G cellular radios, etc, that can't be OTAed. As an example,
my gen 1 Apple tablet no longer receives OTA updates. Again, the point is that the OTA function is limited, generally requiring
a dealer visit to re-flash (if possible) or a new ECU when the update is extensive or critical to vehicle safety.
Edit: Clarified time.
