However, it's important to note that:
* Daimler's Omnibus was more of a prototype than a commercially successful bus.
* Other inventors were also experimenting with engine-powered carriages around the same time, including Karl Benz.
* The first mass-produced bus powered by an internal combustion engine was the "Benz Patent Motorwagen" in 1895, also by Karl Benz.
So, while Daimler's Omnibus is often credited as the first engine-powered bus, the true origin of this invention is a bit more complex.
