Brian Peoples is a social idealist or utopian what is talking about as far as roads of tomorrow with driverless cars and trucks is generations in the future. I am one of those that still like simple technology as hard wired phones and computers. As far a roads, trains and buses goes look a Amsterdam, while it has tons and tons of bicycles there use as short range transportation about three miles and rely on other forms of transportation to get around. We should go easy on tearing out unused rails on the west coast and save them for emergency reserves if the Middle East heat up onto a major shooting war and are supply of oil get cut off rail might be the only we will be able to move vast amount of supplies around.
