Insurance in SA dono if it works different in France does pay for own damage.
Reason for this is due to the liability to the finance house, and other parties. Even though in cases like drunk driving is seen different as it's intentional, you drank and knew driving drunk is a bad idea. As opposed to overtaking on a blind rise which is stupid, but insurance can't reject your claim for stupidity.
Hope it makes sense
As an example: If someone sets their house on fire, on purpose insurance will decline the claim. If however you are having a braai inside your house and add petrol to help it ignite will probably be covered, intentional and deliberate, no. Stupid definitely
