Driving pleasure


Driving pleasure is a feeling of enjoyment derived from operating a motor vehicle. Factors known to contribute to driving pleasure include responsiveness of the vehicle to driver manipulation of the controls, which means that the vehicle obeys and executes driver's commands faithfully.

In the vehicle development process, driving pleasure is "the driver's feel for vehicle manipulation under various road conditions.” When designing a car, features that increase driving pleasure and safety may work in opposition, forcing engineers to make choices between the two or find a new solution that accomplishes both.

Forces are due to acceleration, linear and angular. Longitudinal forces are due to acceleration and deceleration, and lateral forces occur while turning act on the driver. These forces can not be easily simulated anywhere other than a vehicle. Lateral force is available only in a four wheeled vehicle, and can be up to 5g in F1 racing. In motorcycles lateral force on the driver is zero even when cornering, due to leaning the bike into a corner to nullify lateral force.

Back Seat Driver

A back seat driver is a passenger in a vehicle who is not in control of the vehicle and appears to be uncomfortable with the skills of the current driver and/or feels the need to tutor said driver.

Some backseat drivers exhibit this type of behavior simply because they feel unsafe or out of control since they are not driving the vehicle and therefore are nervous and jumpy and overly anxious to give suggestions and criticisms regarding the current driver's actions. The Maine Department of Transportation has a web poster "Are you a Good Back Seat Driver?" asking "True or False: Being a Backseat Driver means it is okay to be noisy or distracting to the driver as long as you are giving them safety tips." The Inland Register produced by the Roman Catholic Diocese of Spokane makes use of it in a sermon: "Even our phrase “back-seat driver” reflects this new-found freedom. Which of us who has graduated to the status of driver enjoys a passenger, especially one out of reach in the back seat, which seems to know how to drive better than we do?

A famous example of a back seat driver is Hyacinth Bucket on the British sitcom keeping up Appearances. The term is also used in Backseat Drivers from Beyond the Stars, an episode of Invader Zim A poem "The Backseat Driver" by Parick G Hughes appears in the Northern Ireland BBC Writer's Showcase.

It is even used as a deliberate game. In All things Considered on NPR for July 19, 2006, there is an account of a "Back Seat Driver competition in Forest City, Iowa. ... The event -- in which a driver races backward while blindfolded and instructed by the voice of a companion over an intercom -- is in its eighth year." It has even been noticed by People's Daily.

Aggressive Driving

Aggressive driving is a form of automobile operation in which an operator will deliberately behave with contempt towards other drivers and drive in such a manner as to increase the risk of an automobile accident.

Unlike drunk driving, aggressive driving is not usually the result of a drug or chemical, but rather the personality of the person operating the automobile. An aggressive driver may adopt a "King of the Road" attitude and become offended when other drivers engage in such activities as passing or "cutting off" the driver. The aggressive driver will then take the actions of the other driver personally, and seek to retaliate. This normally leads to unsafe driving acts such as reckless speeding or attempting to run someone off a highway.

Aggressive driving can also lead to much more serious crimes, such as manslaughter or murder. An aggressive driver may drive so recklessly as to injure or kill another driver or, in extreme cases, will "hunt another driver down" and then deliberately attempt to harm the person. This is often known as "road rage".

Aggressive driving may, in rare cases, be caused by mental illness. Persons with mental diseases, who are driving, may become confused about where they are and who the drivers around them are. This could lead to fear, panic or other emotions causing the person to start driving aggressively.

Automotive vehicle design

Automotive design is the profession involved in the development of the appearance, and to some extent the ergonomics, of motor vehicles or more specifically road vehicles. This most commonly refers to automobiles but also refers to motorcycles, trucks, buses, coaches, and vans. The functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included in automotive engineers.

Automotive design in this context is primarily concerned with developing the visual appearance or aesthetics of the vehicle, though it is also involved in the creation of the product concept. Automotive design is practiced by designers who usually have an art background and a degree in industrial design or transportation design.
