Drive By Wire.. Advantages/ Disadvantages

Drive-by-wire, DbW, by-wire, or x-by-wire technology in the automotive industry replaces the traditional mechanical and hydraulic control systems with electronic control systems using electromechanical actuators and human-machine interfaces such as pedal and steering feel emulators. Hence, the traditional components such as the steering column, intermediate shafts, pumps, hoses, fluids, belts, coolers and brake boosters and master cylinders are eliminated from the vehicle.

Advantages

Safety can be improved by providing computer controlled intervention of vehicle controls with systems such as Electronic Stability Control (ESC), adaptive cruise control and Lane Assist Systems. Ergonomics can be improved by the amount of force and range of movement required by the driver and by greater flexibility in the location of controls. This flexibility also significantly expands the number of options for the vehicle's design. (Y)

Disadvantages

The cost of DbW systems is often greater than conventional systems. The extra costs stem from greater complexity, development costs and the redundant elements needed to make the system safe. Failures in the control systems can result in an unstoppable runaway vehicle - if the throttle, ignition and transmission are all beyond the direct control of the driver there is no effective way to stop the vehicle in such an event.

In a couple of runs my cousin did when his friend got a new Civic in '06 and ran it against his Altis, the Civic felt slower. But on Auto, the civic was faster off the line than the altis (which was manual).
