In the recent period, the whole person has entered a bottleneck period. Annoying things make life and thinking like a knot. Therefore, during this period, from books, networks and other channels to pursue some forgotten knowledge and love, give yourself a buffer period. In a video of exploring the car design in the 80 s, I was surprised that the car conceptual design in the 80 s was so amazing, the concept car of the 80 s has a unique design style and design concept, as well as an almost rhapsody vision for the future. Among them, Citroen Karin's pyramid-like appearance left a deep impression on me. It is rare to stimulate a brainstorming brain hole in the bottleneck of the brain. Perhaps this brain hole is a little rough. In the future, perhaps the design style of the car can really return to the vision like cyberpunk in the 80 s to develop.
