Questão jurídica principal
Whether the injured driver was a co-holder of the accident vehicle under Art. 58 SVG
Decisão extraída
The driver was not a co-holder; decisive control over use and costs remained with B.________.
Fundamentação extraída
The SVG uses a material holder concept. Regular use, fuel payments, and shared travel plans did not transfer dispositive control; the holder was the person deciding who could use the car.
