How can the Federal Highway Administration possibly think a "driverless car" is a safe mode of transportation when the Federal Railroad Administration is studying improved safety standards for railroads that will require locomotives to have TWO engineers in the cab instead of one?
A train has much less variation in its mobility than a car. Who really believes that requiring two operators in a train and ZERO operators in a car makes any sense?
easy.
Interstates were built to not have intersections like Railroads.
What makes trains unsafe is that they have to cross roads. That is not an issue with the interstates.
The railroad union, obviously!
