Just got my (big, ugly) California HOV Lane stickers. Not crazy about how they look, but they'll save me a lot of time in traffic. The positioning of the stickers is mandated (one on right rear, one on each side near rear), but That leaves a lot of leeway for aesthetics. I've seen a lot of cars with them and note how they position the stickers. Haven't seen a Model X with them yet. Where did you put yours? Photos welcome!
