The steering wheel is also powered, allowing the driver an easier time on the steering wheel.An automatic vehicle is also less tiring especially in slow moving traffic. The car automatically engages gears, leaving the driver free just to concentrate on the road, balancing on the brake pedal. Some automatic cars however require the driver to engage a low gear in the slow moving traffic jams. Unlike the manual cars which consume large amounts of fuel in the jams, automatic ones do save on the fuel. The automatic transmission also reduces the chances of making errors with the gear or the clutch. This means there are reduced chances of causing accidents with an automatic car as compared to the manual ones. When carefully driven, the automatic cars provide the driver with many controls over the gears. An automatic gearbox is also a great relief for the elderly and the disabled persons. They also offer a solution to people having difficulties in driving manual cars. The safety of the car is to a large extent dependent on the type of car used whether manual or automatic transmission.There are high chances of drivers with cognitive problems to fail a driving test when using manual cars due to problems of multitasking. Cognition involves the memory, judgement and the speed of response. Aging drivers will most likely have cognition problems. Age does not directly affect the performance of drivers but has an indirect effect resulting from age-related complications such as perceptual, cognitive and psychomotor abilities. The cognitive problems will pose real problems when using machinery, for instance, a vehicle. There is divided attention as such drivers try to concentrate on the gears and clutch. The main problems associated with multitasking will result from the inability to coordinate some sensory aspects. Such a driver will likely fail in some of the clinical tests as discussed below:One of the tests would be a vision test. In addition to just reading the typical eye chart, the driver’s vision has to be examined in great detail. The tests for vision will include peripheral vision, depth perception, visual-spatial skills, and contrast sensitivity. Depth perception will help in the determination of a safe following distance. The depth perception will help the driver to make informed decisions on the directions to take while driving. The driver will be able to decide whether to take a left-hand or right-hand turn.
