HOW TO DRIVE A MOTORCAR
the considerate treatment of the engine and chassis
might quite probably work out at something approach-
ing 20 per cent. In addition to this, at higher speeds
r.e, wear may be. said to increase, roughly, as the cube
oi the speed, whilst the whole chassis suffers to some
extent through the extra strain and jolting put upon it.
Then, again, the life-bearing productions of nature
are not the only things which get tired. Metals have
a knack of getting tired, and continual running under
maximum power with considerable jolting is the best
known means of producing the fatigue of the metals,
rrom all points of view, then, more particularly that
of economy, it is advisable always to make a practice
of merely indulging in the full depression of the throttle
tor snort stretches, or for hill-climbing purposes. It
must be admitted that, every now and then, when ft
fane stretch of road presents itself, one has the right to
enjoy the exhilaration of putting the car to its utmost
speed, but this should be the joyous physical exception
rather than the mechanically-murderous rule.
One may admit that it is usually advisable to
accelerate up to a good speed by the full use of the
throttle, but when that speed has been attained it is
rather surprising, if careful notice is taken, how far
throttle opening may be reduced without materially
decreasing the speed of the car.
In Traffic
I he remarks which have been made relative to the
use of the throttle in general are particularly applic-
able m reference to traffic driving. Do not be tempted
to overdo the “ hang-on-the-top ” idea, and when it is
requisite to pick up with top gear engaged from a very
slow speed take particular care not to open the throttle
too quickly. . Not only will the sudden jar on every-
thing be detrimental to the chassis at large, but from
slow engine speeds on touring cars the acceleration is
not hkely to be so good with a too-quickly-opened
throttle as with a gently manoeuvred one.
Frequently, when having come down to quite slow
running, one can pick up again without any undue
