Instead of spending more and more billions on the rail project, that amount of money could be spent not only to solve traffic congestion on the H-1 but also to solve traffic congestion on state roads such as Kamehameha and Farrington highways and in downtown Honolulu.
It is really sad and tragic that the people and the leaders of this island do not really know that Traffic Congestion has either been solved or minimized in several mainland cities thru modern technology - the kind of technology  employed in self-parking and self-parking cars, the kind of technology employed in the US Missile Defense System, in stealth aircraft, etc.
The thing that commuters who drive cars would really love to experience is the Green Light Tunnel technology used in Topeka Kansas that enables drivers to go thru many intersections with Green Light and experience Congestion Free Travel
