My 2014 came with the white HOV stickers. This is all new to me, I only got the car in October. I live near Los Angeles, fortunately I don't drive freeways much, think I've only used the HOV lanes once or twice with the stickers, when traffic was flowing pretty well. I drive the Leaf conservatively (IOW, slowly) and got tired of being tailgated by other cars, so I got out pretty quickly and just tooled along on the regular lanes. So I won't miss 'em much when the stickers expire, but obviously if I was commuting every day in stop & go traffic, they would be a godsend. I've actually met several EV drivers who say we shouldn't get to drive in the HOV lane. I wouldn't go that far, just enjoy it while it lasts.
