"Roberts intertwines McGregor's corporate, civic, and personal lives to trace his pioneering role in the automobile industry. Some themes from McGregor's career that are considered here include company growth, the technical and cultural concept of the automobile, the impact of automotive transportation, technological reliance on Detroit, parent-branch relations, the effects of border proximity, industrial and political lobbying, labor relations, secondary manufacturing, public involvement, and the Great War. In addition, Roberts probes McGregor's often-subservient relationship with the enigmatic Henry Ford and examines how McGregor drew praise and political ire in calling for regional governance in the "Border Cities" opposite Detroit. In the years before his premature death, McGregor and his company dominated and defined the growing automotive industry in Windsor-Detroit, and their story deserves to be more widely known.".
