I've noticed that every concept car I see looks the same; sort of a swoopy Prius like car with very little headroom. I don't think I want one of these in the future. I want the rounded car with lots of headroom in Sleeper. Granted there are problems with the tiny sliver of a window and it would no doubt bottom out on the easiest of bumps, but it's pretty swell. I also like the pod-like cars on Logan's Run. Again, the lack of a steering wheel, seat belts, or any radio could be an issue, but cool design trumps these.
Dale Hennesy was the production designer on Logan's Run and Sleeper. Both of these have that distinct glossy and slick 1970s futuristic vision. Plastic is big. Chrome is hip. All white interiors like an Apple store or the new Enterprise work well. The furniture is made for awkward lounging and would clearly pose problems when it was time to stand up. Also, it must be quite temperate in the future. The people in Logan's Run seem to wear draping silk scarves as clothing and are really into those low socks. In this story, people are killed at 30 to maintain population control. Given the lack of arch-support if you only wear socks, this is a positive. Otherwise these people would be limping around at 40.
Most importantly, I appreciate the Garanimals approach to clothes. Monochrome is big. Nobody has clashing patterns or colors. Everyone is very matchy matchy. Perhaps people go home and change into plaid pants and flower patterned shirts in private.
