Yarises? Yars? Regardless, via John (who found it via Jalopnik), I found this patriotic organization of automobiles from a Derbyshire Toyota factory:

Apparently “a crack team of 40 yard drivers and workshop technicians spent two 12 hour shifts reversing, turning and parking 400 Toyota Yaris cars into a giant St George’s Cross.” Who was building the cars in the meantime?
Now, if only they could drive the thing over to Berlin for the final. Mind you, England won’t be in it, but it’d be a charming PR stunt.
