"Totally 'street legal' & very expensive (about USD150,000 each) conversion.
Yes, you read that right; these little beasties are street legal. They run on either Kawasaki or Honda motorcycle engines and co-opt vintage bumper car bodies into the most awesome form of mini-car we've seen in too long. There are seven of these little monsters floating around California, and they're all the creation of one man, Tom Wright, a builder in the outskirts of San Diego who figured the leftovers of the Long Beach Pike amusement park needed a more dignified end than the trash heap. They were originally powered by Harley motors but they rattled like hell and Tom replaces them with Honda or Kawasaki 750's and a couple have been measured as capable of 160 MPH (257km/h), which is terrifyingly fast in machines with such a short wheelbase.
