1.What the feature is and how it makes the car safer?
Stopping a car in a hurry on a slippery road can be very challenging. Anti-lock braking systems (ABS) take a lot of the challenge out of this sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can't stop as quickly without ABS as an average driver can with ABS. This is because ABS brakes prevents the wheels of a vehicle locking as brake pedal pressure is applied, often suddenly in an emergency or short stopping distance. 2.The science behind why the feature makes cars safer?

ABS brakes don’t lock meaning that the wheels will have static friction, which allows the wheels to maintain grip without sliding out of control. ABS brakes allow the car to have static friction instead of sliding friction by a computer turning on and off the brakes rapidly, and therefore the car can maintain control.

3.What researches lead to the development of this feature?
ABS was first developed for aircraft use in 1929, by an aircraft pioneer Gabriel Voisin, as threshold braking on airplanes is nearly impossible. These systems use a flywheel and valve attached to a hydraulic line that feeds the brake cylinders. The systems use where extremely out dated to today standards but very effective in fact, in testing, a 30% improvement in braking performance was noted, because the pilots immediately applied full brakes instead of slowly increasing pressure in order to find the skid point. An additional benefit was the elimination of burned or burst tires. In the 1950’s, ABS brakes where used more often but still only on aircrafts, the system was improved to reduce braking distance on all surfaces by 30%, increase tire life, it helped with landing and taking of also. In 1960s experiments where done to find that ABS brakes would be useful to motorcycles/automobiles, however little future was seen in the system and it was not put into the production company. The first fully electronic anti-lock...
