I have had a low speed No1 failure in the simulator and it is tricky. The nose wheel is sliding before you know it. Closing the thrust levers and disconnecting the auto throttle; the engines still take a while to spool down plus by the time they have, you already have rotational inertia so it will keep going even with the differential thrust removed, the nosewheel has already lost traction so is doing little to counteract the spin. Differential braking would help, but a normal RTO uses auto brakes which you would disengage by applying foot braking, so that is not your first immediate reaction. By the time you have processed what is happening and that you require manual braking, you are already headed for the side of the runway. If you were quick enough on the brakes and moving slowly enough when the problem first occurred, you will stop before leaving the paved surface, but I can imagine there is a 'sweet spot' where you would not stand a chance of avoiding it in the real world.
