Agree or Disagree
No disagreement here.
I was really surprised to find that John Dinkel's Dictionary of Automotive Terms did not include a definition for automobile; I guess, it was assumed if you know what an automotive dictionary is you know what the definition of an automobile is.
A couple definitions of automobile from other sources:
Main Entry: 2automobile
Function: noun
a usually four-wheeled automotive vehicle designed for passenger transportation

automobile: Chiefly
US, 1886, [a.F,] A. . Self-propelling, B.
sb. A motor vehicle. Also as vb.
The etymology indicates the word is adopted from French, which may lead us to believe that the French should be credited with the first automobile.

This source explores automotive development by components, in the engine portion:
"But for the truly significant advance of the motor car in the closing years of the 19th century, the honours go to two Germans, Carl Benz and Gottlieb Daimler. Benz and Daimler, operating separately, built compact engines running on volatile inflammable liquids such as light petroleum spirit and naptha. Both of these engines were soon developed for motor vehicle propulsion."
"...Benz and Daimler made cars powered by internal combustion engines for sale, so it can be said in the modern context that they were the true founders of a way of life. Plaything, status symbol or necessity, whatever the meaning of a car to mid-20th-century man -- it all really began with these two inventors."

This source is more historically based and follows the evolution of the various steam engines and those prior to the internal combustion engines.
"...and Edouard Delamare-Debouttebville, assisted by his faithful and skilled mechanic Leio Malandin, built a four-wheel car in France with a high compression engine fed on a light essence of petroleum. Features such as overhead valves and a power rating of about 2.5 hp show the degree of sophistication attained. However, in spite of the fact that by many this was at the time considered the first automobile, Delamare-Deboutteville failed to exploit his work on an industrial scale and his name disappeared from the history of the motor car."
"...Meanwhile, another German, Karl Benz, the owner of of Benz & Company in Mannheim, developed his own engine with electric ignition and brought out a three-wheel vehicle in 1886 which, because of the perfect integration of its engine and chassis, can be considered the first true automobile."

So depending on if you use the "automobile" definition based on The Oxford Universal Dictionary of "self-propelled" or the Merriam-Webster Dictionary of "'usually' four-wheeled vehicle" your choice of who invented the first automobile will differ. As I said previously, there is probably not a clear definitive answer without first deciding on the focus or definition of "automobile." However, having said that, I've not found in any of the cited sources any reference to Stu's Italian connection.
