This is true. No problems pedalling with 45 km/h on a flat road.

This effect increases with lots of luggage behind me.
Also keep in mind, that e.g. on a 16% slope, the steering angle
changes and the "pendulum effect" vanishes.

Pedalling is a good remedy, I have learned.
So far, no differences found when braking rear or front wheel.

:-)
RWS must be real fun and I would like to try it once.
But this cannot be the solution because I want to steer my
bikes without hands and this is not possible with RWS.
