That's not comparable at all. McDonald's basically sold an unsafe food, so they were liable. Food companies, restaurants, etc. are held to a certain standard for what they service.

Other than being inaccurate (every map ever made is inaccurate), can you explain how Google is responsible for a driver's skill or ability to pay attention to where they are going?

There have been some wild cases of people using in-car navigation and driving off dead ends, into water, etc. We laugh and call them idiots. What else can you do?
