Not sure why we do not get at least the option in the USA, but Euro spec i3s have the outside 1/3 or so of both side rear view mirrors optically expanded to capture pretty much anything that might show up in our typical blind spot. There is something of a dotted line that separates the 1:1 view from the expanded view, and it becomes instantly intuitive. In my opinion, it is a far simpler and more elegant solution to the blind spot problem than an idiot light. My guess is that some moronic USA regulation prohibits its use here, and BMW wisely chose to wait for us to wise up and change our rules rather than add a needless layer of complexity to the fraction of their i3 fleet they sell here.
