There was some truly fantastical stuff imagined in the 1950s [1]. I’m particularly fond of the GM “Firebird” self-driving jet-turbine cars [2]. They prominently featured various winglets. Not sure if they were there just for futuristic looks and jet-age appeal or if they were intended for the kind of use you describe.
