Whoda thunk it? One industrial designer specialized in weird super-streamlined trucks. This Vintage.es article shows a weird 1936 armored car, with an elevated cupola for a tailgunner, designed by Everett Miller.
The article mentions that Miller also did the Gilmore fuel oil neon truck and the Arrowhead Spring Water teardrop car. The latter reminds me of Bucky Fuller’s Dumbaxion Car. Bucky got there first in 1934, so Miller was probably copying him. Both are stupid and utterly impractical. There are good reasons for traditional ways of arranging an automobile, just as there are good reasons for traditional house designs like the Bungalow and Cape Cod. Structures shaped by experience work better and last longer than Innovative Disruptions.
Basic rule: Creativity needs EDITORS more than designers. A good editor can reject stupid or unsalable designs.
