Questione giuridica chiave
Whether the cantonal court arbitrarily assessed the distance and violated in dubio pro reo
Decisione estratta
No. The distance finding was supported by the police report, officer testimony, and the photograph, so the evidentiary assessment was not arbitrary.
Motivazione estratta
The officers could reliably estimate the gap from their professional experience; the photo showed lane markings and shadows allowing a sufficiently precise reconstruction.
