Norman Foster's concept car updates Buckminster Fuller’s Dymaxion

Architect Norman Foster can add car designer to his résumé. Foster’s zeppelin-shaped design is an updated version of the 1933 Dymaxion, an 11-seat vehicle originally designed and built by architect/engineer R. Buckminster Fuller. Among the car's more curious features: a periscope instead of a rear-view mirror and steering via the single back wheel.
