Antilock braking system

Many modem automobiles are now equipped with an antilocking braking system. Explain in terms of and fit why this is advantageous. 

Antilock braking systems with quickly reacting independent wheel decisions based on current and acquired knowledge... 

Infinity antilock brake system (lABS), designed quite recently, looks like any other antilock brake system. The pulsing rate of the shoes against the drum, however, is not constant but rather increases in speed as long as your foot is applied to the brake pedal. The system is guaranteed to stop any car in an efficient manner. (When I inquired about the lABS at my Mitshbishi 3000 dealer, I was told that this device was not yet available.)... 

Question Are the brake shoes on or off the dmm at the end of the second For a number of physical reasons, it would be difficult to actually design an infinity antilock brake system, but let s discuss this in a theoretical manner for the moment. You seem to have all the necessary information to determine whether the brake shoes are pressing on the dmm or not. Additionally, the shoes have to be either pressing or not pressing. What is your answer ... 

Some of you are probably arguing that the rapid pulsing required in the infinity antilock brake system just described may cause an overheating of the brake dmm and shoes, despite the use of cooling fins bonded to the outside of the brake dmm to increase the rate of heat transfer to the air. Vents in the wheels to increase air circulation for cooling also may not reduce temperatures sufficiently. Therefore, I introduce a less mechanically stressed system, the infinity keyboard.

In a 1999 workshop, a well-known Canadian human factors scientist delivered a lecture on behavioural adaptation (BA) and the potential safety benefits and risks of the widespread introduction of antilock brake systems (ABS). The scientist was contemplating whether or not it would be prudent to order ABS brakes when purchasing their own new family car. The conundrum at the time was the increase in accident rates (cf. Kahane, 1994 Hertz et al., 1995) among drivers of cars equipped with ABS compared to those whose vehicle was not so equipped. Erroneously, many drivers may have overestimated the effectiveness of ABS and adjusted their behaviour inappropriately by braking later and harder, and by...
