What about leaning your weight? I have seen that other people can rather

Vary the pressure (weight) slightly between the pedals on the downstroke
or stop pedalling with the lower foot in the direction you want to turn
and put a little weight on it. (Either way, you tilt your hips a bit in
that direction.)
