You have grey areas, but I would tell you the culture and the oversight around safety is much more disciplined. You have a federal regulator, whereas if it's product performance, it's provincial; and the provinces, even though they have good laws on the books for defective products, don't actually have any muscle and are not really even engaged with the carmakers. That's why you have class actions, unfortunately. Often the reason that you wait until you have thousands of unhappy people is because the gatekeepers along the way are not actually effective.
I would say in most cases, yes, there are some grey areas. The brake booster is one. Ford's argument was if your brakes are lousy, go and get them repaired. The vehicle will still stop. It's just the booster. That's not the brakes. That's just the booster. Transport had another view, as did some of the vehicle owners.
