THE CLUTCH PEDAL
second, which can make such a difference when travel-
ing at speed between having an accident and just
missing it. It is a fairly reasonable limit of time after
many careful tests—to state that when one has the
left leg in a position of rest, some three or four-fifths
of a second elapse from the time when the mind has
become aware of the fact that it is necessary to de-
clutch, before the foot is actually on the clutch pedal.
Now, that minute portion of time is equivalent at 20
miles an hour to some 6 yds. or 7 yds., and the extra
amount of momentum gathered in running that dis-
tance with the power of the engine still being passed on
to the car compared with having declutched so many
yards sooner is quite an important factor, when it is a
case of missing an accident by a very narrow margin.
When one thinks how often an incident in driving is
only prevented from being an accident by a matter of
a foot or even inches, the intrinsic value of these odd
fifths of a second is readily seen to be very much
greater than their apparent or superficial value.
The idea is put forward, therefore—admittedly as no
more than a suggestion—that the reader should en-
deavour to cultivate this method of training himself to
be quite comfortable with the left foot resting
directly on the clutch pedal for the greater part of his
driving. When touring in the counti’y a little rest or
change is required (the spot of greatest safety can
always by chosen), but for town work and villages, and
where cross-roads are continually being negotiated, the
writer invariably has his foot directly on the clutch
pedal waiting there to make the necessary movement
without the loss of those valuable odd fifths of a
second, and never after the first month or two of train-
ing has he experienced the slightest trouble or fatigue
in so doing.
To qualify this statement in order to make it precise
in view of actual facts, it is, of course, necessary that
the position of the clutch pedal and the seat relative to
the driver’s stature is more or less correct. If the seat-
ing room is very cramped, then, of course, it must
prove tiring, but for those who habitually drive but one
