Driving on the wrong side of the highway is an extreme example, but going to England from continental Europe by car can have a similar result.

Leaving your blinker on will confuse other drivers, who will think you're an idiot since it actually makes a noise and flashes on your dash.

Let's hope we get it. I need more rabbits to sweep up the cops. I'll be content driving slightly slower and less conspicuously than this guy.
