If only the Hop and the RTD Eco-Pass get enough funding, the problem will be abated. If only enough bike paths are constructed, it will make a difference. Good grief, many of the buses running now are all but empty. And plenty of people could not or would not use a bike as an alternative. Automobiles appear to be cost effective.
Cars are more convenient because they can be driven from door to door, anytime the driver likes.
And thanks to government subsidies for roads and highways, the driver doesn't have to pay the full cost of his driving. This isn't necessarily a pipe dream. The request is passed to a jitney operating in the area, which stops by to pick up the passenger, together with other passengers headed for similar destinations. If necessary they can rendezvous with another vehicle to complete the trip. Some taxi companies are already experimenting with this kind of technology.
