False. The ABS does the pumping for you while you control the vehicle to a stop.
If you want to maintain your steering, yes.
a safety system which prevents the wheel on a motor vehicle from locking while braking.
false
Being able to steer and control vehicle while panic braking. Being able to steer and control vehicle when braking on ice/snow.
An anti-lock braking system, or ABS (from the German, Antiblockiersystem) is a safety system which prevents the wheels on a motor vehicle from locking while braking. A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to continue interacting tractively with the road surface as directed by driver steering inputs.
An anti-lock braking system, or ABS is a safety system which prevents the wheels on a motor vehicle from locking up (or ceasing to rotate) while braking. anti lock brakes were designed so that when you do a "panic stop" or slam on your brakes, it will control your wheels so they dont slip or loose traction.
Everything you do with a car goes thru the tires, braking, acceleration and handling.

True. Anti-Lock Brake System (ABS) is a system that allows the wheels on a vehicle to maintain tractive contact with the road surface according to driver inputs while at the same time braking, preventing the wheels from locking up and thus avoiding skidding. With ABS you can brake hard and still have control.
If by "mobility" one means the "operation" of the vehicle, there are a ton of sensors on modern vehicles. Many are associated with engine operation and performance. And we integrate more and more sensors into vehicles all the time. The ABS braking system is a sensor driven system that maximizes vehicle braking performance by preventing the wheels from locking up (and, thereby, the tires' traction from "breaking" with the roadway). There are lots of sensors on cars, and it might take a course on vehicle mechanics to get a handle on them all. And those don't count the ones associated with climate control, audio and video systems, etc.
This is the traction control of the vehicle, preventing uncontrollable skidding in hard braking or steering situations.
