That pretty well describes the actual experimental phase of the
automobile in our society.  People came up with, and built, all sorts of
designs before eventually coalescing around Ford's - and that was as
much due to breakthroughs/advantages in other related technology (the
process of manufacturing them) as any innate superiority of the design
itself.

Considering the significant benefits of standardization, the most
plausible way I can think of to keep such a varied situation past the
introductory/early-adopter period is if there are several major players
who all stubbornly insist on maintaining and promoting their own
partially or wholly incompatible "standards".  This state of affairs can
persist for as long as the market is unable to pick a decisive winner,
possibly until the development of a next generation of the technology
renders all of the previous moot.
