Laws of question

May the venerable Gaon Sheki live for many days.
One day, as befits,
If it is possible to ‘steal’ his time and ask for forgiveness to ask a question that I was asked,
An incident involving five yeshiva K students who were traveling on Shabbat to their rabbi and a shishvak, who borrowed a car from one of the students, when only one of them had the ‘legal ability to drive’. On their return trip, one of the students who was sitting next to the driver held the ‘Waze’ device and informed the driver when he was facing, etc., and further along the road there was a ‘Fin’ and a roundabout ahead, but he waited for a while between them and at the roundabout he had to continue straight and the shishvak did not inform him that the guy who was holding the Waze device, and he was driving there too late in responding and there was an accident in the car.
And everyone asks together, so who is responsible for paying the damages?
