Well, if they're going to show it in all it's glory next week, why release a teaser so close to that date? Probably something that can do burnouts like those skid marks.
More effective because it gets people talking more than just seeing what they`re getting. Especially when you consider all that was going on at the time and what hints someone can get from that picture. All of that combined fuels discussions.Ultimately, do you think that it was a more effective teaser than one that actually shows some actual part of the vehicle?
