For cars with internal combustion engines, the company tends to get constant income via service thanks oil filters, other filters, and a whole bunch of stuff that needs to be replaced (assuming people take it to authorised service centers, which I assume most people do when the car is relatively new).
With the transition to EV, those avenues dry up because EVs need lesser maintenance (as per my understanding).
So, are they trying to create new recurring income sources due to the possibility of existing such incomes drying up?
