Legal Question in Telecomm Law in California

Why not? You could do a remake of "Weird TV" (which featured a camera mounted in the passenger seat aimed at the show's emcee, Chuck Cirino, who drove and simultaneously narrated the "Comfort Zone" segments). Or you could point it forward or backward. Or you could mount little tiny cameras at all angles and Drive While Black and maybe document some racial profiling or other police misconduct. Go crazy. The only thing you can't do is have a monitor visible to the driver while the vehicle is in motion.
