Key legal question
Whether the cantonal judgment violated the right to be heard by failing to address a key argument on the vehicle's left-turn maneuver and traces of braking.
Extracted holding
The complaint was not pursued further because, in any event, the Federal Tribunal found the conviction unsustainable on arbitrariness grounds; the cantonal reasoning was at least implicitly sufficient.
Extracted reasoning
The first judge considered the appellant's theory of an abrupt left turn and rejected it implicitly by treating the motorcyclist's insufficient distance as decisive.
