Clarification by a simracing bore
Just to clarify a few things here, it sounds like you're talking about Bono Huis who won the Las Vegas eRace at CES back in January. Refering to him as "the Dutch champion" in the context of the article is incorrect, as this is the first incarnation of the virtual Formula 1 Championship.
Bono Huis is a multiple champion of various amateur/semi-professional sim racing championships, including "Formula SimRacing" in which current real-life F1 driver Stoffel Vandoorne competed in.
In winning the Las Vegas eRace (organised by the electric-only racing series "Formula E" not Formula One) he won a sizeable chunk of the US$1,000,000 prize pool (over $250,000 I believe).
The biggest hotshoe in F1 at the moment is the dutchman Max Verstappen, who is an honourary member of the sim-racing team "Team Redline", the same team as Bono Huis. A video of Max Verstappen practicing in the iRacing.com simulation showed him pulling off an overtaking maneuver at the Belgian racetrack "Spa-Francorchamps" which he replicated in real life at the 2016 Belgian Grand Prix causing nerds everywhere to rejoice.
Also worth mentioning that the Mclaren Formula One Team are currently holding a "World's Fastest Gamer" competition, the winner of which will win a contract to be a test driver in their Formula 1 Simulator at the Mclaren Technology Centre.
"Simracing" is my thing, sorry to be a bore! :)
