Hyperloop: Not so fast
I remember hearing an interview with a civil engineer about why highways have all these "unnecessary" curves in them. Why can't engineers build highways that are more direct and straight?After going on a bit about requirements for different kinds of terrain, the kind of strata the road needs to go on etc. and how those were difficult and expensive to surmount (so curves were often chosen to deal with it instead of a more expensive solution). He lamented that the most difficult and expensive aspect of new road construction was right of way through existing developments and other properties. Most of the curves we experience on highways are apparently the result of somebody, or a block of people, simply not wanting to give up their land.
