Wow @carlos84

what an amazing comment. You're not from India so I was quite surprised to see your feedback :)

"When man only transported himself by walking, the technology of transporting himself on horseback emerged, when the first horses began to be sold perhaps it did not seem a profitable business, since the first people had accidents on those horses, which is why other people saw such technology of horse transportation as something risky, however as time went by horse transportation became safer and the business of selling horses was profitable."

This example would make more sense if you would stick to story about car instead of horse :)
People used to ride horses even before money has been introduced.
