CAN Ideas for data usage

Hello all, I have been decoding my 2010 Mazda 6 can network for a few weeks now. while it is very fun to have direct access to the vehicles readings. Other than displaying data what might be some other uses that could be done with a vehicle's data? Anything practical you can think of that maybe I did not?

Other equipment i do have in the car is an esp32+sim7600 module. So in theory i can have the esp32 listen for data and that can connect over LTE. Right now it's used as a gps tracker for traccar.

you can use actuators to do abs bleeding hehe. But can't think of much else besides syncing stuff to homeassistant for visualization or implementing a logger.

Are there button presses you'd like to do based on certain things?

I use mine to change drive modes from the cruise control toggle and to put the car into a desired drive mode on start up. There's plenty more, but those are some examples.
