Actually, if I read it right, the base truck would be built with all the added technology, but you would have to pay for activation. It makes sense for the manufacturer, in that ALL vehicles go down the line and are built the same. If a customer wants heated seats only, and not a package, they pay only for that upgrade, and it is either a subscription, OR a one time purchase. A subscription might be monthly, and could be canceled or inly paid for when needed, as in, heated seats only for the winter months. And, if you leave the vehicle parked for an extended time while traveling, you would suspend the upgrades while it is not being used. for some people, cafeteria style upgrades might really be the thing. For me, I would rather buy an upgrade outright because I keep a vehicle for a longer period of time than most.
I am sure that people raised the roof and went all snowflake when someone put a motor on a buggy a few years back, and look where we are now. Cant be without one.
