Spitballing here, the transition to Electric Transport Trucks and associated charging infrastructure could introduce more slack in an industry where speed is usually top priority.
At an intermodal facility, often time is wasted waiting to load/unload, which could be spent to recharge. For local distribution, charging at home base seems feasible and efficient. For long hauls, where hours of service, tiredness management is concerned, with adequate spacing of charging infrastructure, trucks can be charged during rest breaks.
