Kernrechtsfrage
Whether the appeal could succeed on the alleged violation of the presumption of innocence and challenge to the factual findings.
Extrahierter Entscheid
The appellant relied on facts that were not capable of affecting the outcome; the cantonal courts based their conviction on the appellant's own statements, and the appeal did not show a legally relevant error in fact-finding.
Extrahierte Begründung
Under Art. 97(1) LTF, only factual allegations capable of affecting the outcome matter on federal appeal. The appellant did not contest that he began a U-turn without first checking the mirrors to ensure he would not obstruct or endanger other road users; the complaint therefore could not be examined on the merits.
