It is a good idea, because we feel as though we have chosen a technological marvel already belonged to us.In many cases, customers decide to change already taken the decision after testing the vehicle.
Increasingly, test drive is also used by people who really do not plan to buy a new car straight from the living room (we have because in this case the count of the really high costs), but I just want to ride a selected vehicle due to, for example, interest in Automotive whether the nature of the work.
Cars are equipped with controls used for driving, passenger comfort and safety, normally operated by a combination of the use of feet and hands, and occasionally by voice on 2000s-era cars.These controls include a steering wheel, pedals for operating the brakes and controlling the car's speed (and, in a manual transmission car, a clutch pedal), a shift lever or stick for changing gears, and a number of buttons and dials for turning on lights, ventilation and other functions.Modern cars' controls are now standardised, such as the location for the accelerator and brake, but this was not always the case.Controls are evolving in response to new technologies, for example the electric car and the integration of mobile communications.

An electric motor uses electrical energy to produce mechanical energy, usually through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy, is accomplished by a generator or dynamo. Traction motors used on vehicles often perform both tasks..
Electric motors can be run as generators and vice versa, although this is not always practical.Electric motors are ubiquitous, being found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives.They may be powered by direct current (for example a battery powered portable device or motor vehicle), or by alternating current from a central electrical distribution grid. The smallest motors may be found in electric wristwatches.Medium-size motors of highly standardized dimensions and characteristics provide convenient mechanical power for industrial uses.The very largest electric motors are used for propulsion of large ships, and for such purposes as pipeline compressors, with ratings in the thousands of kilowatts.
Electric motors may be classified by the source of electric power, by their internal construction, and by their application.Źródło: https://en.wikipedia.org/wiki/Engine#Electric_motor
