However, animals on their own, though used as a means of transport, are not called vehicles, but rather beasts of burden or draft animals. This distinction includes humans carrying another human, for example a child or a disabled person.

"The next evolution is presented in Euripides. He is less ideal than his predeccesor, but truer to nature. His drama is more of a reality. He takes his stand in the midst of human life as it is. His language is the language of the people. The heroes of his plays are more possible than those of Sophocles. They are redeemed with weaknesses, touched with folly, stained with tears. He has more variety in his action, greater freedom, more surprises and vicissitudes."—Ridpath, 1885

"We see here a towering cliff belonging to a mountainous range which rises like a wall, or barrier, between the neighboring portions of the same country. The inhabitants desire very much to have a free communication with each other, but there is a mountain barrier which it is extremely difficult to get over, or around; they, therefore, determine to go through it. The human will brings to its aid the powerful elements of fire and water. Gunpowder and the steam-engine work wonders - they force a way through the solid rock. The iron railway is made, and the traveler, instead of toiling through long tedious hours over a mountain pathway, in a few moments, while in an easy chair, finds himself on the other side."—Barber, 1857
