Tuk-tuks have the potential to become a hype in western countries. This is not only because this form of transport has a lot of advantages (mobility) in crowded cities, but also because it is a sustainable alternative for taxis. The growing focus on sustainability in cities in the western world (helped by programs such as the Clinton Climate Initiative) stimulates technical innovations on tuk-tuks. In the Netherlands, technical universities battle to organise the first hybrid tuk-tuks. Hybrid tuk-tuks just might become a hype in western cities to battle both transport and environmental problems.
