One of the more enjoyable aspects of being a designer is when we are granted the opportunity to develop concepts. It allows us to imagine what the future may hold, while also painting a target for engineers and developers to ultimately build toward. As time marches on, there's a certain amusement that comes from reviewing old visions and concepts to see how closely we imagined future realities, or where we were totally off-base.
The 1969 Buick Century Cruiser was a technology-laden concept car created by Buick, based on the Firebird IV concept. The basis of their vision was that in the future, there would be automated highways, where steering, throttle, and braking by the driver wouldn't be necessary.
