In the end, the KIA car company made its cars into subscription models, I really hate this because in the end the car we buy with our own money doesn't feel like it belongs to us. Should we finally buy an old school car ? so as not to be affected by this subscription models or is there a way to crack the software installed in it ?
All of these functionalities can be provided by a simple WebSocket + REST server. The car connects to the WebSocket, and you can access these functionalities from your phone either with WebSockets or regular HTTP requests.
Cheapest servers with backend written in JS can easily handle thousands of WebSocket connections, and written in Go tens of thousands WebSocket connections. They would not ever need like over 100 of these servers GLOBALLY, which would cost them around $3000 monthly.
That's the price of 60 subscriptions, which is freaking ridiculous.
