I guess this depends on how well cars with mandatory subscriptions sell compared to before. If the number of sales goes up, or stays the same I would guess more manufacturers start doing this. And I'd say this is the slippery slope from smart home devices all requiring a subscription. Since everything "smart" requires backend infrastructure and cloud bills can't be paid for the entire lifecycle up front, get ready to see a lot of subscriptions added to things that didn't have it before.
