Dublin trafic

You are never going to give up your auld cars, are you? Especially not your shiny new cars. After seven (or is it eight?) hundred years of oppression you DO want to step in to your new cars and hurtle yourself freely along the streets of Dublin at...is it six miles an hour at rush hour?
So you sit in a brand new shiny car with blackened windows and roll down the road at six miles an hour. That way you can combine an "almost Latin disregard for time" ( I quote Benedict Kiely - I don't make all this stuff up, you know) with the satisfaction of knowing that your car COULD also move at 150 miles an hour.
Makes sense, eh ?
