Connecting an EV means getting better battery efficiency over time.
I work with batteries in the EV industry (not inside cars, though, but lithium-iron-phosphate), and the list of planned improvements is not short.
There’s a gap between when a product is ready to be used and when most of the known optimisations are done. And there’s a big risk factor with the company suddenly deciding to depreciate your thing.
I try to only have only “dumb” appliances in my home: kitchen, washing, lighting. If I couldn’t avoid buying with wifi, it doesn’t get enabled.

Then ask for wifi credentials, or ask to connect through a phone. If I don't connect a device, it's because the device is not allowed to be connected. Any device that thinks it's important enough to ship with its own SIM card using an account I don't control, rather than putting the user in full control of connectivity, is a device I will never purchase.
Better to go with one which pairs with your phone if you even need this functionality.
