Questione giuridica chiave
Whether the cantonal court arbitrarily relied on the medical expert report and violated the presumption of innocence by rejecting the claim of an acute loss of consciousness.
Decisione estratta
The report was coherent and convincing; no serious reasons justified departing from it, and the court did not shift the burden of proof to the defendant.
Motivazione estratta
The expert excluded epilepsy, cardiac causes, and vasovagal syncope, and plausibly concluded that the accident was caused by brief sleep while driving. The complaint was largely unsubstantive and appellatory.
