We have had our 2015 i3 for just over a year now and I would love to see the addition of a reverse alert. On several occasions in parking lots, I have had people walk behind our car when backing up out of a parking space. A friend of mine recently bought a Leaf - even the Nissan figured it could be a problem. The same tone used on unlocking the doors could be utilized for this function. The next time you guys are doing a software upgrade - pls consider this safety feature.
