Hi Dirk,
I like your second suggest even better, and will report back when I can convert
the rear hubs to fixed gear. Also, thanks for coining the term "social
steering"; I am tempted to add more independent python drives to explore our
social limit...

Hi Vi,
you could have a handle with a sidearm and then a long rod to another sidearm
connected to the frontpart that does the steering.
Otherwise, you could stick to your social steering approach:
the rider cycling on the outside of a curve would just have to speed up a
little
:-)
The python frontend should follow, if i'm not mistaken, since it now has
negative trail again in addition to pendulum effect...
regards,
DirkS
