1. They have cut-outs for the mirrors that limit their effectiveness against wind and rain. This is due to the JDM folding-mirror which was not brought to the US (not sure if that was a cost cutting measure or if they weren't "approved" in the US yet).
IIRC, the JDM mirrors actually fold in automatically when put in park or engine shuts down.
Don't think it was that sophisticated, they were controlled by a switch that goes in the blank spot beside your heated mirror switch. Pretty sure you had to do it yourself.
