this is the main reason that i (personally) don't like "traditional" holonomic setups. mecanum/ilon wheels (such as the ones on these robots) solve this problem to a degree, since it allows you to harness the power of all 4 motors whenever the bot is moving in a direction perpindicular or parrallel to that of wheel rotation. this setup is weakest when it is moving diagonally when only two of the wheels are being powered. in addition, since the rollers overlap, and are rounded, there isn't as much bumping present as there is in the traditional omni-wheel.
