Questão jurídica principal
Whether the cantonal court's fact-finding and identification of the driver were arbitrary.
Decisão extraída
The challenged fact-finding was not arbitrary in the result; the motorcycle could be attributed to the accused on the totality of the evidence.
Fundamentação extraída
The Federal Court deferred to the lower court's assessment of the radar photo, vehicle registration, color change, ownership, and witness evidence. Mere alternative explanations and appellatory criticism did not show clear error.
