The basic principle of turn is balancing using the centrifugal
force which makes vehicle go outside and the gravity which
makes vehicle fall inside.
The centrifugal force increases in inverse portion to the radius
of a curve and in portion to the square speed. Decelerate prior
to entering the curved way to reduce the centrifugal force.
