I really hope they don't use this to autopilot cars. That seems completely reckless. If a terrorist happened to get an LED flashlight that disrupted the transmission of whatever light signals were going to the autopiloted cars, there would be chaos. It would be so easy interrupt these signals.
Thinking more about it, any signal "controlling" an autopiloted car would be insecure and be an easy exploit that any malicious-minded people could take advantage of. But that's a discussion that's besides the point.
