Model S has been around for seven years now, so Tesla has a pretty good idea of what breaks and what doesn't.

One of the advantages of having an electric car is that they require much less maintenance than a comparable vehicle powered by an internal combustion engine.
Tesla takes advantage of this after crushing the data in recent years with service and vehicle data by moving away from a recommended annual service program to one that only requires vehicles to enter when parts need replacing. [1
An EV does not have engine oil to change, nor do the manufacturers produce the same type of heat as petrol or diesel engines do. Parts are not exposed to the same type of extreme temperatures.
With brakes, many EV drivers use their vehicles with high levels of regenerative braking. This uses the fuel to lower the car and charge the battery and saves considerable wear on the car's brake components. However, brake fluid will still be controlled every year for water pollution.
Add to the fact that Teslas is online and has robust external diagnostic functionality, and an annual check seems even less necessary. Tesla representatives are quick to point out that this shift in service methodology has nothing to do with a Tesla warranty, and vehicles that need service can get it.
Tesla will stop pushing its prepaid customer maintenance plans, but will still respect plans that have been sold. It seems likely that the "required" service system will end up being cheaper than a prepaid customer plan anyway.
