Marketing of cars has very little to do with facts, it's all about emotion. There are no pictures of the typical congestion, its all open roads with no other pesky road users. The models are all slim whereas most of their customers struggle to drag their fat backsides into the car. The kids are happy to sit in the back whilst the reality is they will be screaming "are we there yet" after five minutes of a long drive.
