I strongly suspect that the "speak with your local dealer" is where
all of this started, and the user installation part came after. There
ARE shop scan tools that do a block-flash right off the dealership's
network, and those have been around for 15 years. Only dealers can buy
them, and they need an expensive dealer service login for the downloads.
Then, as more vehicles were sold, and lower models were brought out
with the feature, there was more need to provide a way for third
parties to do this work, so the USB method (which was only for storing
owner-specific stuff not to be lost like routes and waypoints, but
HAPPENED to copy anything on the drive when it restored) was introduced,
then the shade-tree mechanics and high school boy racers yammered for a
way that they could do it without 13.5V power supplies, so this "run the
engine" thing came out as a compromise.
And that it went from high to low models because the high-end models are
the ones that can afford the time for the car to go to the dealer for an
expensive upgrade with an accompanying "easy for dealer, hard for anyone
else" update model. It's all compromises for the lower-end and home
maintenance ends of the market, and the stupidities are dealing with
"how do we make this happen safely and without corruption, when we don't
have a 13.5V shop power connection and a CAN-SCAN 6000 available?"
