I feel bad for you and what you have gone through, but I am calling a little bit of BS on this.
It is not a pothole...it is a layer of asphalt that has peeled off from the under layer, resulting in a 1 to 1.5 inch drop at the most...nowhere anywhere close to require such an evasive maneuver that would cause you to flip a car. I drove over that exact same hole a week ago, same as the cars in the news report who are going over it without flipping their cars, and it was nowhere near being as deep or dangerous as you make it out to be. Don't get me wrong, I am not defending transport Quebec on this issue, as the conditions of our roads are indeed inadequate, however I think you are looking for an excuse to justify your driving error by pointing the finger at someone else.
Instead of manning up to an obvious driving error, you cry to the first person who will hand you a tissue and rub your back. Maybe you should run to Fox news next, they love this type of stuff.
Sorry for the reality check, but I just had to get it off my chest.
