Approach the groove diagonally,
and allow one of the front wheels
to drop in.
Time your acceleration so that the
inertia of the vehicle will be able
to carry the tire over the groove.
Once the first wheel has cleared
the groove, allow the other front
wheel to drop in.
Time your acceleration so that the
inertia of the vehicle will be able
to carry the tire over the groove.
Also, take care not to allow both
the tire which is dropped into the
groove and the tire at the oppos-
ing corner to fall into the groove at
the same time.
Bring the rear wheels over the
groove in the same way as the
front wheels.
Time your acceleration so that the
inertia of the vehicle will be able
to carry the tire over the ditch.
