Display Planned SoC in Android Auto

🚧 THIS IS A TICKET MIGRATED FROM UPVOTY. The original ticket and comments will be available for a limited time over at:

———————————————————————————
The Android Auto display shows live Data SOC, and the calculated SOC on arrival at next waypoint. A useful feature may be to add (either by default or by a setting) the calculated expected SOC at the current position, much as can be seen in the advanced graph view in the App. This would allow users to immediately see discrepancies between their plan and the live data, and make judgements as to whether the plan is valid.

This would be especially helpful for new users, who could gain confidence in the SOC prediction, as well as experienced users, who could see if a change to settings they have made has had an adverse impact.

To make this work in the Head Unit interface, rather than a graph, just the current percentage could be displayed (the value shown on the graph in Blue).

Further, if this could be displayed for the expected at waypoint value as well, that could also help identify where the plan was made incorrectly, as during the drive the discrepancy would visibly change.
