Can electrons flow in opposite directions on the same wire, see schematic!

See if the wire showing electron flow in both directions was not there, as in we remove the wire from point A and point B then all three batteries combined as an external path is not enough power to run the led and the motor. However with the wire from A and B in place the motor runs at the speed that one battery would give it and the leds brightness is the brightness of two batteries. So to me it still seems we have electron flow going in both directions at the same time on the same wire, from point A and point B. Electrons always take the path of least resistance, its the taught law. And even if this is incorrect, if electrons take all paths, and not the path of least resistance, then we still have electron flow along the same wire at the same time, going in opposite directions, as all paths taken would mean this.

I will try to make this as simple as I can.

When you connect to the center of the two batteries, that junction becomes 0-Volts, AKA ground or earth, in respect to the other two poles, the far left pole becomes -1.5V and the far right +1.5V. You should also notice, if you have connected both motors correctly, that the two motors spin in different directions (I think but I may be wrong), this is because the polarity at one end is mirror image to the other. You should also notice that each motor is only receiving 1.5-Volts.

Disconnect the vertical center green wire, then both motors should spin in the same direction, this is because now the far right positive end is 3-Volts, in respect to the far left negative. With that wire disconnected, one motor will speed up if the other one is labored or stalled, very handy for a differential effect in a model car or robot.

That kind of circuit is simply a voltage splitter, very handy for reversible speed control circuits.

Thank you all very much,,I will certainly put forward some thought into this.

If I remove the middle wire that goes up and down, in the center, there is a change in motor speed, a very noticeable change,
...

Either your batteries or your motors are not perfectly identical or their rotation are not a synchronized. In this last case, there is probably an AC current in the common wire (check the current with an oscilloscope)

The electrons flow because they are submitted to a force F=q.E where E in the electric field in the wire. The direction of the force is the same for all electrons and all electrons are identical thus there is no crossed flux of electrons.
