Even if we just ignore the Netherlands, bike riders aren't being doored left and right in Denmark either. Sure "The Dutch Reach" is a clever trick to get people to look out for bike traffic, but really it's just common sense.

Like in the Netherlands, bike lanes in Denmark are mostly placed between the road and the side walk, so by not looking out for trafic you risk getting your door torn of by an SUV, rather than hitting a bike.
