I tell you what, the Australians are pretty crazy. A Lotus Exige GT3 passed between a Mazda Miata and Porsche Boxster with hardly any room to spare. All of this took place at Australia's Island Magic Enduro 2011 race, so thankfully this crazy stunt was pulled on a race track and not on a public road. In any case, there was no crash, no injuries and good video footage. The video below is taken from the Miata.
