Future of new EV market

In the recent years there is boom in EV (Electronic Vehicles) market. Some are telling that EV has less problems than normal such as change in engine oil, brakes etc. We can see tesla truck converts friction applied on brakes to electricity and no removal of pedals even with two engine it can run. And less customers will be going back to showroom or repair less. I think this is going to effect the profit of EV companies. I use a car for every 10,000 km i have to travel to a show room of the company and change fluid(paying more) and the usual problem with not updated GPS. Due to some other reasons people also want to go EV than petrol. My question is how EV companies are going to make profit out of this. Are they going to start subscription service model like credit cards(premium features) and ads if you want to start auto pilot for every few kilometers you have to see an Ad etc or premium charging stations.
