Have you seen a video of it at night? That blinking could cause a seizure. I don't like signs that put photosensitive people at risk. Also, it's being held up by sandbags which could mean that the sign isn't exactly stable (probably not up to code, too) and could ruin someone's car (by falling on it) and/or kill them. Also, Elon Husk has denied inspectors access to the roof, which further adds to the sign "not being up to code". Also, the lights are blinding even when they're NOT giving you a seizure
