&gt; Things involving humans (vehicles cutting you off, pedestrians, etc.) are part of the general class of problems that I&#x27;m assuming all automated vehicles are working on and are much harder.<p>The more mass you have, the longer your braking distance and the more sluggish the reactions. While the problem is the same, and the mechanical differences easily modelled, light vehicles get away with lower accuracy and higher latencies, because they don&#x27;t need to plan ahead so far.
