> Trucks are way more complicated to drive. Once they're up to cruising speed, they're easy. But it'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. The mechanical aspects of controlling a large truck and accounting for the variables is probably the easiest part of the problem. Things involving hum…
> Things involving humans (vehicles cutting you off, pedestrians, etc.) are part of the general class of problems that I'm assuming all automated vehicles are working on and are much harder. 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 l…
The article mentions 45mph as the most efficient speed for a truck. I can imagine the regulators demanding a pretty low speed for automated trucks.
