Will be interesting to see if car features become subscription based. Currently manufacturers derive the majority of their profit on the initial sale. Once the cars are on the road they don't see a penny of profit for most of them(ok, there's parts and servicing but the competition is generally cheaper). If they could derive profit throughout the lifetime of the vehicle it would encourage a decrease in the churn rate of cars. Currently, the used car market only indirectly drives profit for them (resale allows the initial buyers to attach greater value to their purchase).
