Why? As a driver of another car, what exactly am I expected to do when I see a car in some kind of autonomous mode? It&#x27;s not like reversing lights or turn indicators, which give a hint about what the driver is about to do.<p>If the &#x27;autonomous mode lights&#x27; are meant to be some kind of warning, then that&#x27;s just telling me that an autonomous mode isn&#x27;t fit for real world use yet.
