&gt; Trucks are way more complicated to drive. Once they&#x27;re up to cruising speed, they&#x27;re easy. But it&#x27;s everything leading up to that point which is hard. Dealing with gear changes, airbrakes, load shifting, other vehicles that will inevitably cut you off, and much more.<p>The mechanical aspects of controlling a large truck and accounting for the variables is probably the easiest part of the problem.<p>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.
