Just a point of correction here. Turning off VDC does NOT turn off the ABLS. Also the ABLS will not really slow you down.
The VDC is basically skid control and it is capable of reducing throttle if it senses a skid. It would keep sensing wheel spin and keep backing the throttle off and in this case bring you to a standstill. It can be vary irritating in the circumstances you describe so that is why you would want to turn it off.
The ABLS is a separate system that attempts to provide traction by sensing a wheel that is spinning and then applying braking force to transfer power to the other wheel so you still have traction. You can not turn off the ABLS system and there would be no reason to want to.
