He got that one solved pretty good though, in spite of lack of market research.
About 3 years ago a friend named Ed A. who owns a Ford Model-A took me out for a spin and it was surprisingly quick for it's very small engine, it wasn't the fastest of the mark but that didn't stop it from accelerating all the way to 100 km/h.
The difference between a steady 100 km/h and a horse is quite large, in fact we haven't gone much beyond what the Model-A could do in day to day driving situations.
