If you ever feel cars are getting too expensive, consider yourself lucky you don't live in Singapore. The country, an island located on the tip of mainland Malaysia, is smaller than most cities, and one of the most prosperous nations in the world. Due to its (lack of) size, traffic is a big problem--so the government levies huge taxes on cars to discourage their use. Which is why a Toyota Prius costs $154,000 over there--over six times its cost in the U.S. Interviewed by Singaporean TV program RazorTV (via Car Throttle), Fast & Furious series star Vin Diesel is less than impressed with the price of the well-known gas-sipper.
