Has anything been done with this with bicycles? *It would certainly

Yes, it is called "through and off" and the computer that controls it

line 2. The chain goes clockwise or anti-clockwise depending on the
wind direction, to give shelter to the faster line. On a club run we
will usually have the outside line as the faster line - as this works
better in traffic
