Kernrechtsfrage
Whether the cantonal court violated the appellant's right to be heard by not hearing his passenger as a witness.
Extrahierter Entscheid
No violation: the court could refuse the additional witness after anticipatory assessment of the evidence, since the written statement already covered the relevant facts.
Extrahierte Begründung
The appellant did not indicate any specific additional facts the testimony would prove; the court was sufficiently informed.
