Comment: Left vs. Right ;)

"Nonetheless, the power of the right has been growing steadily. When Germany annexed Austria in 1938, it brutally suppressed the latter's keep-left rights, and much the same happened in Czechoslovakia in 1939.
On 12 March 1938 Hitler invaded Austria, and the next day proclaimed Anschluss, the absorption of Austria into Germany. He ordered that the traffic should change from the left to the right side of the road, overnight. The change threw the driving public into turmoil, because motorists were unable to see most road signs. In Vienna it proved impossible to change the trams overnight, so while all other traffic took to the right hand side of the road, the trams continued to run on the left for several weeks. Czechoslovakia and Hungary, the last two states on the mainland of Europe to keep left, changed to the right after being invaded by Germany in 1939."
