John and Horace probably would have been happy to have continued to make parts for Ford, because they were making a lot of money and had a 10% stock ownership in the Ford corporation, except that they thought the Model T was too primitive, and they grew to dislike being associated with it. They wanted Ford to modernize his car by featuring a water pump, distributor-type ignition and an electric starter. When Ford kept refusing to entertain their ideas, the Dodge brothers decided they'd better make their own car.
