One thing I've noticed is that whenever I use autopilot, my wheels get a lot dirtier a lot faster. I almost never use the brakes when I drive, but it seems like AP uses them waaaay too often. I'm a little worried about long term brake wear. But in the mean time, I would like to gather some real data. What CAN buss(es) would I need to monitor braking events as well as autopilot status? Any idea what the specific codes are? I want to set up a long term logger to gather this specific data from the car over time.
