Question juridique clé
Whether the cantonal court established the facts arbitrarily, especially witness credibility, speeding, unsafe distance, and crossing a safety line
Solution extraite
The factual findings were not manifestly inaccurate or arbitrary; the witnesses were credible and the challenged findings were supportable.
Motifs extraits
Federal review is limited to arbitrariness. The testimony was consistent overall, corroborated by other evidence and the collision itself; the appellant's alternative version was merely appellatory.
