It is not hard to get all four motor to run at the same speed. However, as you said, under stress two of them will act as generators. One of the way to prevent that is to somehow disengage those two motor. I am not sure you can do it in the program, but mechanically it is possible.

One option is to make your own gear box, and disengage gears in that to disconnect the motors from the wheel. Second option is do what Team Choas did last year, which is instead of 2 wheels with the Fisher Price motors, you have those two wheels on one side of a lever and two free spinning ones on another side of the lever. Using a window lift motor to spin the motorized wheels on the ground when you want more force, or spin the free wheels on the ground when you want to move easily.
