I wonder how many retired speedway riders there are, who have been mentally scarred, by being called a 'bad name' by the rest of the team, management or promoter?
Yes, Noah Moss is half Danish and half Korean.
Thomas Sörensen was half Danish and half Sri Lankan.
... and that young German lad You mentioned is Mario Häusl (see picture below), whose father is from Munich and his mother from the Seychelles.
He is even sporting the national flag of the Seychelles on his kevlars. He must be the first speedway riders ever to emerge form these Indian Ocean islands.
