I mean why would you bother? It's not like it would be important in a study on them. In fact, I bet they've never even seen a car. I hear they still use the un-horseless carriage in Warwick.

You can buy systems like that now for use in communications. Light is already used in cars in millions of cars in MOST and FLEXRAY systems which control car operating, safety and communications/entertainment systems. We've seen it used in engine management systems in race cars and proposed for ignition systems. But line of sight optical has the same problem it has in longer outdoor links - signals being obscured by dirt or moisture (fog and clouds.) Have the people proposing this ever looked under the hood of a car? I first saw a demo of a system like this (line of sight optical) in an IBM lab in the mid 1960s!
