During those hearings they didn't talk about how they would protect the driver or what material the truck would be made of or the casing that the stuff is in. I remember them saying that being next to one of those trucks was comparable to having an xray.
I know that transporting by air was not an option. I know that currently the power plants are handling the transportation and storage within the various states.
I think the idea of transporting that stuff cross country is very scary.
