Kernrechtsfrage
Whether the cantonal court's factual finding that the motorcyclist was not speeding was arbitrary.
Extrahierter Entscheid
The finding was not arbitrary and could not be overturned on federal appeal.
Extrahierte Begründung
Federal review of facts is limited to manifest error/arbitrariness. The submitted 'expertise' was not a true expert report and did not compel the conclusion that the motorcycle was speeding; the alternative interpretation of the circumstances was insufficient.
