"The automaker next year will turn CarPlay into a subscription-based service rather than treating it as a one-time option, Don Smith, technology product manager for BMW North America, told The Verge at the 2018 Detroit Auto Show on Tuesday.

"This allows the customer to switch devices," he said. "A lot of people buy [CarPlay] and think it's okay, but sometimes they stop using it or switch to Android." "This allows the customer to switch devices"

I understand it as a switch from the current $300 option for ACP - as I paid for my 2018 M2 - and adding it as an annual subscription item you can cancel. For those of us who have it currently at the $300 option add-on, it's a done deal; nothing in the purchase contract specifies a switch to a subscription model.
