You have a point. How often/long do you wash your car, and how much $ do you spend on this? I have to admit, I do not wash my car very often. Pity they did not report anything about the cost of deploying the "dirtophobic" car paint film. If one could make it a quickly applicable, inexpensive "spray and go" option that allows to regenerate a dirt repelling film - why not. But there must be a reason why "Nissan says it has no plans to offer the paint as standard equipment, but will consider making it an option".

I am also wondering why they neglected the windows in the video clip. Might be a problem with transparency of the film, or a difference in the nature of the film adhesion to regular paint and glass. It is a pity that they did not provide any data on mechanical stability and film degradation. Without this data, I still do believe that this is a PR thing. Alas, it is wired.com.
