Key legal question
Whether the federal court was bound by the cantonal finding that the driver travelled at 60-70 km/h and failed to adapt his speed to the circumstances.
Extracted holding
The cantonal factual finding was not manifestly incorrect and remained binding on federal review.
Extracted reasoning
The final criminal penalty order relied on the police report; the driver knew the administrative measure depended on the criminal case, and his later contrary account was found not credible.
