I have a Tesla here in Australia, and have 3-4 charging apps and 2 RFID(!) cards -- it does feel like a backwards step. There are gaps in the Tesla supercharger network in parts here which mean you have to rely on the other networks for some long distance trips.

But what about gas? Race track, loves, shell. They all offer gasoline discounts if you have their app.

But, crucially, you can ignore all that and just pay with a plain card, or even cash if you want. EVs need to match that.

To be clear, they pretty much already do. There are only a handful of companies that require an app install. Filtering chargers nearby by company/tap-to-pay is probably a few months away from one of the mapping apps.
