I’m not an expert or anything, but my masters was focused on driving technology, and specifically the intersection of technology and sociology. A conclusion I often felt drawn to is that, while humans are still the drivers, the technology will always lack efficiency.
Charging highway is a neat idea but having it shared between vehicles like trucks which try to travel a consistent speed, and cars which change lanes etc, means that I think the human factor will complicate the process (and safety) to a high degree.
There are a great many advancements we can make to automotive technology if we reduce our reliance on a human driver.
