I watched that video and I'm wondering how they knew they were tourists and not just local distracted drivers. Did they stop the cars and interview the drivers? Lots of people in the US die every year in head on collisions by drivers on the wrong side of the road - not necessarily tourists.
Don't get me wrong, I know how hard it is to drive on the left when you're not used to it, it takes concentration and constant vigilance. And I'm all for the campaign. But it's not just tourists concentrating on the scenery. It's distracted driving in all it's forms - cell phone usage, looking at gps screens rather than the road, reading, lack of proper sleep and alertness, etc etc etc.
