horse can travel at the rate of two and one-half miles an hour
raising a weight of one hundred and fifty pounds, and the horse
can do more; while it cannot move so heavy a weight as
thirty-three thousand pounds, it can in an emergency and by sudden
strain move much more than one hundred and fifty pounds; with good
foothold it can pull more than its own weight along a road, out of a
hole, or up a hill. It could not lift or pull so great a weight very
far; in fact, no farther than the equivalent of approximately
thirty-three thousand pounds raised one foot in one minute; but for
the few seconds necessary a very great amount of energy is at the
command of the driver of the horse. Hence eight horses, or even
four, or two can do things on the road that an eight horse-power
gasoline machine cannot do; for the gasoline machine cannot
concentrate all its power into the exertion of a few moments. If it
is capable of lifting a given load up a given grade at a certain
speed on its lowest gear, it cannot lift twice the load up the same
grade, or the same load up a steeper grade in double the time, for
its resources are exhausted when the limit of the power developed
through the lowest gear is reached. The grade may be only a mud
hole, out of which the rear wheels have to rise only two feet to be
free, but it is as fatal to progress as a hill a mile long.
Of course it is always possible to race the engine, throw in the
clutch, and gain some power from the momentum of the fly-wheel,
and many a bad place may be surmounted step by step in this way;
but this process has its limitations also, and the fact remains
that with a gasoline machine it is possible to carry a given load
only so fast, but if the machine moves it all, it will continue to
move on until the load is increased, or the road changes for the
worse.
When the farmer hears of an eight horse-power machine he thinks of
the wonderful things eight good horses can do on the road, and is
surprised when the machine fails to go up hills that teams travel
every day; he does not understand it, and wonders where the power
comes in. He is not enough of a mechanic to reflect that the eight
horse-power is demonstrated in the carrying of a ton over average
roads one hundred and fifty miles in ten hours, something eight
horses could not possibly do.

Here's a piece of wisdom on driving or cute car quote to study:
Americans are broad-minded people. They'll accept the fact that a person can be an alcoholic, a dope fiend, a wife beater, and even a newspaperman, but if a man doesn't drive, there is something wrong with him. ~Art Buchwald, "How Un-American Can You Get?," Have I Ever Lied to You?, 1966
