First Car Built on Assembly Line By Marcel Brown | 2 January 14, 1914 The first car to be built on an assembly line was completed today, a Model-T Ford. Posted in Miscellaneous Technology Scot_Kroozr In the good ol’ U.S. of A., where we conduct large-scale social experiments WITHOUT PLANNING THEM FIRST, this is the day we set out to equip the entire population with cheap cars! Marcel Brown Given that Ford was a privately owned company, I wouldn’t say this was a social experiment in any way. Nor in a free country should a government be planning society either. History (and current times) has shown that central planners do a terrible job anyway.
