The conspiracy theorist might surmise that this is another example of EU encroachment on national sovereignty ... didn't Eire have a problem with EU rules being imposed without the will of its people under its Constitution? So far Eire and the UK have resisted Schengen (which was backdoored by the Amsterdam Treaty).
Congratulations on another EU impost: 16% (or thereabouts) mandatory VAT imposed without representation: gotta love the United States of Europe!!
If you go to the Daimler museum in Stuttgart (Bad Cannstadt) you will find that early German vehicles' steering wheels were on the right side (so that drivers could see the ditch just like coach drivers ... nothing to do with drawing swords).
