Marginally on this topic: I saw something weird yesterday...a 4th generation Prius with white HOV stickers (rear and left side, didn't see the right side). There's no way in the world that could be legit, right?

I've seen cheaters since I moved to CA. Cars that are even Hybrid carrying HOVs or I've seen some ebay looking HOVs on a Tesla as well.
I usually take pictures of the vehicle with plate # to report when i see them especially while I am using AP.
