Puzzle through this classic ethical dilemma and decide: is community safety more important than individual privacy?

--

Your government has introduced a plan to address record-breaking rates of traffic tickets and deadly hovercar accidents. They propose assigning “driver credit scores” to every citizen, but would need to install cameras and microphones in every vehicle. While it would make the roads safer, is this undeniable benefit worth the cost to drivers’ privacy? Michael Vazquez and Sarah Stroud investigate.

Lesson by Michael Vazquez and Sarah Stroud, directed by Jeff Le Bars, JetPropulsion.space.
