The guideway is wide enough for the self driving cars of today and tomorrow.  Today we have self guided buses that are very small.  In the next few years, electric transit buses will be a regular site.  Turning the guideway into a self driving Managed Lane is the best solution.  The guideway as planned does not make good use of  the space.  24 rail cars per hour on an elevated two lane highway is wasteful.  Combining self driving transit vehicles and Managed Lanes will be superior to rail in every category - speed, capacity, lower cost, safety etc.  Adding self driving vehicles for emergency use, and personal use will increase guideway usage and decrease vehicles from H-1.  Self-driving transit buses can provide all the transit that is needed in a TOD development as well.  A self-driving vehicle Managed Lane is the smart green choice.
