Created here out of a thread that gained life in the Investor forum. We got to talking about train vs. semi efficiency (diesel and electric), and then platoon / convoy efficiency. So in my vocabulary, trucks in platoon and trucks in convoy are the same thing (namely - incremental trucks after the first that are using software and driver assist technologies to follow a lead truck closely). Whether the 2nd / 3rd / etc.. trucks also have a driver on board is related but different - I can see early implementations where the later trucks have a driver on board, but those drivers can nap / watch TV / take a break, and can periodically rotate lead and follow positions. Later, the follow trucks can be driverless. For the current conversation, this is about the efficiency of the vehicles, and that doesn't change with or without the driver.
