== Nationality of drivers == 

 "The nationality that appears on the racing licence is the same one that appears on the driver's passport. This is not necessarily the same as the country issuing the racing licence. A Frenchman living in Germany can race with a German licence, but the nationality displayed would still be French. In order to race as German, the driver would need to have German nationality as well. Drivers with multiple citizenship choose their "official" nationality." 

 Since he's only a Belgian national and not a Dutch it should state Belgian. I know this case is unique since he choose to race under Dutch flag. But rules should be followed.
