It is exactly this kind of confusion I try to clear up with my article.
The table in the image is an American roulette table.
Yes the wheel features only one zero. And the table betting layout has the racetrack. So we can assume it is probably used in Europe. But the TABLE (not the wheel or the table betting layout) is American.
In fact there is no European table. There are mainly two kinds of tables, the American and the French.
If you read the article till the end you will understand more.
In all over Europe such tables can be found and the game is called officially "American roulette".
Why is it called American roulette, since it is played in Europe, with European wheel and with racetrack bets?
Because this is an American table with American rules (no En Prison or La Partage)
Now with online casinos, everything that has one zero is called European roulette. They are only referring to the wheel, since there is no real table in online casinos. But all this ads to the confusion.
