I may have forgotten a bit of physics here. I thought about the extra pushing power, but wouldn't the secondary/slave wheel for use of a better word. Be producing the same force as if it was directly attached to a motor?!

2 wheels with 1 motor have the power of that motor and the force of that motor divided by 2.
2 wheels with 2 motors have double the force untill you are on just the back wheels when you are being pushed about and lifted at the front. Then you are back to the same as the above.... just when you need the force...
Good, thank you. Must have been a Blonde moment!! Seen a few new builds with one motor, driving two or more wheels, thought I may have been missing a trick or something. More motors equals more pushing power. Sorted. I'd imagine there comes a point where the benefit is outweighed by other factors. Otherwise why no 10 wheeled push bots with 5motors each side!!?
Well the point of more motors is lost when the amount of force is determined by the friction x the weight of the bot. More motors just makes more of your precious weight taken by stuff that does not damage the other guy.
I suppose you would get better acceleration and higher possible top speed but keeping control of the things seems to be more of an issue than speed.
Again the challenge of maintaining force whilst the bugger lifts you you and thus gets all of his drive down and you slide backwards is significant.
