John, you are right that rail isn't the only solution to our traffic problems. Telecommuting, driverless cars, carpooling, etc are all additional solutions. However, traffic congestion isn't the only issue we're trying to solve and rail has a lot of other benefits. Even if people live on the west side, what we are really trying to do is create communities where people can live without the need to drive, without giving up mobility. 39% of Honolulu's population today does not even have a driver's license. Rail, especially high capacity rail, is really good at encouraging ridership because it has the service quality in terms of travel speeds, frequency and capacity to meet the travel needs of far more people than buses or even at-grade light rail.
