undisputed influence or power
“Autocrat” was an antiautomobile cultural meme from the early 1900s, when cars were supposedly toys for the rich and good only for running down children, dogs, and nuns. By the 1912, automobiles had lost the elitist stigma, something William Howard Taft deliberately achieved by promoting the technology as president, so Olds could by then use the term for aspirational marketing.
Heritage has the first presidential auto, Taft’s White: https://heritagemuseumsandgardens.org/hmg/1909-white-steam-car/?portfolioCats=409, a transformative automobile, deservedly in the National Register of Historic Vehicles.
This car, though, is by far my favorite in the Heritage collection:

Magnificent!
