I didn't know and I've been following Telsa closely for years. I wonder if their point that this stuff is rather opaque is reinforced by this, rather than obviated by the specifics of "it didn't stop at 2 stop signs but did stop at others on auto-steer but auto-steer should stop at none" I'm curious what you and others make of the sticker thing -- why is it well-known that specifically a smiley face sticker will disable it? Is the idea that the recognition software just outputs "FACE 100%" because enough is visible on the back?
