Hybrid vehicles have already proven their worth and durability
in big city taxi service in Manhattan over the past two years. By 2012 all New York city taxis
will be required to have at least hybrid
drive-trains. In 2006, officials in Sydney, Australia
started their own hybrid taxi test to evaluate the efficacy of their use. The Toyota Prius
turned out to be a fine taxi and New South Wales Transport Minister John Watkins has announced it has been approved for use as a taxi in Sydney. Presumably other hybrid vehicles
will be added to the approved list as they become available on the Australian market.
