Below is a YouTube video of a presentation regarding “Disruption of Transportation” for the 2020 North Carolina Department of Transportation Summit.
It may be of especial interest here, since at one point the speaker discussess how caravans of autonomous electric semi-trucks could replace railroads.
An who can forget how the High Speed Rail Plan in the ARRA (“Stimulus” bill) was replaced by the much lower-cost High Speech Bus Plan, where cost-effective meal service was to be provided by allowing the lunch-wagon guy to board the bus to sell food?
Problem with electric semis is batteries and charging thereof. Fast charging requires a lot of power which effectivey means that the charging stations need to have some hefty energy storage system to meet peak demand.
