answer:I think there would be a more viable alternative than the Carro Publico, but never having visited that island trust territory of the USA, I don’t know what it might be. I’d suggest that a kind of “laboratorio de ideas” be impaneled to carefully study the problem and come up with possible solutions. The “experts” for this group should consist of life-long residents of the island, who are specialists in the field of population density studies and mass transportation. Also, one of the ways to make any kind of “bus service” popular, is to have it operate 24/7 (but with decreased frequency during the late-at-night or early morning hours) and to have the fares funded by taxpayer dollars (subsidized), so passengers can ride free of charge.
