> As some cars gain more autonomy, it's probably helpful if they have a way to signal their intentions to other road users. My first though was exactly that, this looks useful. That said, as I'm thinking about it bit more, it's not easy for me to come up with nice examples of situations when this signal is actionable, clear and useful. I doubt most people understand what level 3 autonomous driving means nor what to expect from a car driving in this mode in a particular situation, esp. when there will be differences across car manufacturers.
