Toyota-Mistake Or Cover Up

 Toyota has been one of the world's great automakers.  Do you think that they did not know about the defects such as acceleration issues and brake issues across the vast majority of their line? When the story first broke, it seemed like a simple issue; not any longer. A corporation is nothing more than a group of people working to achieve the same philosophy;  they should be considered as any individual would----innocent until proven guilty. Personally, I hope that this is a combination of errors instead of a cover up. What's your opinion?
