All we have disputes that can be resolved by a simple googling, but sometimes unusual and non-standard ideas go out of control, the same thing has happened to our heroes. After trying to settle down the question "How high can a taxi meter go" guys bought a black '92 London taxi-cab for $2000 from eBay and started their adventure.
After leaving the U.K. it took about one year to go around the world and settle new world record. Moreover guys visited such places as The Middle East in time for the Arab Spring, Arctic Circle and Mount Everest base camp.
And, finally, the taxi meter went to $100,000. So now you know how much money do you need to travel around the world in a taxi)
