In many cases, the wheels slipping before maximum torque output of the motors is actually preferable. At first, I can see why it might seem counter-intuitive, but it is simply the best alternative.

Something is going to be the limiting factor in the drive train's ability to transmit force to the ground. It can be, among other things:
-Motor torque
-Mechanical strength
-Circuit breakers
-Electrical safety conditions
-Traction

I would rather have my wheels temporarily slip on the ground as opposed to my motors stalling, electronics frying, wheels breaking, shafts bending, gears shearing, chain snapping, belt skipping, circuit breakers tripping, battery dying, or wires catching on fire.

It is not a waste to have more torque available than needed to break traction, it is actually a very good practice in FRC.
