4 years ago I was telling people we would have self driving cars in 5 years.  So I&#x27;m very pleased with the progress.<p>It remains to be seen how effective pumping can be, but as envisioned hyperloop is a point to point system.  Switches are very difficult and must be done at low speed a) because of the slipstream disruption and b) because branching greatly increases the interior volume of an enclosed tubeset.  It can be done.. but it&#x27;s a level above the basic infrastructure.
