Questão jurídica principal
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.
Decisão extraída
The cantonal factual finding was not manifestly incorrect and remained binding on federal review.
Fundamentação extraída
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.
