So I noticed this the other day and decided to see if it would come back. As the battery in my M3 gets lower and lower I see dots beginning to appear on the far right edge of the power meter (see attached photo). The most I have seen is three dots when I was down to about 50 miles of range. Has anyone else seen these or have an explanation of what they are? It reminds me of a 'redline' in an ICE car to show where power output caps, esp. as battery gets lower and theres more of a necessity to preserve range/performance. Will post more photos this week as the dots increase.
