Yay Puddin for the column! It's definitely new. TAR hasn't been anywhere near Stuttgart (nearest venture is Friedrichshafen, Germany and Schauffhausen, Switzerland in TAR3). And here to report, the taxis are Greek!
Zante Radio Taxi Services
They're on the island of Zakynthos, off the Peloponnese Peninsula, geographically closer to Sicily than you can ever get. Hellenic Mediterranean Lines (not the boat in the vidcaps though) offers a service from Bridici (on the heel of Italy's boot) to the island. Could this be the link to Greece?
I'm now searching to see if our ferry plies between Zakynthos and the Greek mainland.
