I learned a variation of the Dutch Reach in my driver's license test (tested in Haarlem, school teaching it Max120). He didn't give it a name or anything and seems like common sense and I think it's a better way than the Dutch Reach described in the article.

When you open the door you grab the door handle -- the thing that opens the door -- with your right and plastic black handle -- the thing that gives you more 'grip' -- with your left. By doing this you have a lot more control on closing the door as well if you still happen to accidentally open it when you shouldn't have.

I had to retract once, because it appeared I had a blindspot where I couldn't see a cyclist.
