You are, of course, utterly right in what you say. It is very much in the interests of car manufacturers not only to perpetuate the private car ownership and usage mindset, but to build obsolescence into the design.
We have an electric car, mainly because my wife needs it for essential activities due to lack of mobility (doctors, pharmacists, etc) and because it is convenient, but there is very much a temptation to increase usage to make life a bit easier, as the car is not powered by fossil fuels. Such as doing the weekly shop by car, rather than carrying groceries back, particularly if it includes a 12-pack of Guinness. And of course electric cars are much more efficient than diesel/petrol over small distances or if you are stuck in heavy traffic. But nothing like as efficient as bicycle / walking, especially when you consider the space required.
Even amongst electric car users, there is still the same usage pattern, with some people doing 20,000 miles a year or more, with many journeys that are not necessary or could be substituted by train / coach travel instead. And the desire to upgrade their car at the next opportunity to something with even features, range and power. Not helped by the charging network moving away from Type 2 connectors, making a change of car necessary for those seeking to do longer journeys. It would be a very brave manufacturer who would make a modular "future-poofed" car that can upgrade the charging, battery, infotainment system, etc, so that existing owners can upgrade to the latest technology without having to buy a new car.
