Hey guys,
There's a member on here that works for Just Car Insurance and I was speaking to him last night in person (Shy_Boi I think his SAU name is).
He said that they WILL pay out a p-plater in a high powered vehicle as long as no police are on the scene to fine them for doing anything illegal (i.e. overpowered car).
He said that they "insure the car, not the driver".
