Thanks to D.K., I could put a name on the strange vehicle spoted in the streets of Copenhagen:

This is a Bubble car (a post WW2 production)! It immediately reminded me of the Cushicle by Archigram… (1966) and the Suitsalon (1967) (BTW, isn’t Orta’s Refuge Wear City Interventions 1993-1998 in the lineage of the Suitsalon? and Italo Calvino’s Invisible Cities, 1972, so related to Archigram? I like hypertexting :) This is to say that I am quite impressed by Archigram’s sensibility toward their post WW2 everyday, and their subsequent mental assemblages.
