For all the negativity here about Musk and his business decisions, there is something to be said for integrating transport and energy services in one great package.

I consult for a large energy conglomerate that wants to get into this market from the energy suppliers side, but the problem is that they are completely clueless when it comes to expanding beyond their traditional business. In their vision, they'll supply customers with solar panels, an EV charger, home battery, heating solutions and as a backup their traditional business: gas and electricity. All integrated in a nice package.

It took them two years to set up a department that sells their first product (besides gas and electricity): an outdated EV charger, from a company they bought that stopped innovating after acquisition and is now lagging behind competition. Not a car, just the charger.
