thumb|right|An electronic odometer (below the speedometer) with digital display showing An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two (electromechanical). The noun derives from ancient Greek , hodómetron, from , hodós ('path' or 'gateway') and , métron ('measure'). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileomet

A tricycle, sometimes abbreviated to trike, is a human-powered (or gasoline or electric motor-powered or assisted, or gravity-powered) three-wheeled vehicle.

The term is derived from two Latin words: pro, meaning before or forward; and pellere, meaning to drive. A propulsion system consists of a source of mechanical power, and a propulsor (means of converting this power into propulsive force).

For road vehicles with more than two axles (for example, some trucks and buses), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck or bus, the wheelbase would be the distance between the steering axle and a po

Telematics is an interdisciplinary field encompassing telecommunications, vehicular technologies (road transport, road safety, etc., as part of Intelligent transportation systems), electrical engineering (sensors, instrumentation, wireless communications, etc.), and computer science (multimedia, Internet, etc.). Telematics can involve any of the following:

transparent display presenting data within normal sight lines of the user

secondary function of the electronic stability control on production motor vehicles, designed to prevent wheelspin of the driven road wheels

component of a vehicle or other device that safely stores its fuel

safety glass that holds together when shattered, consisting of multple layers of glass held in place by interlayers

A defogger, demister, or defroster is a system to clear condensation and thaw frost from the windshield, backglass, or side windows of a motor vehicle. The rear window defroster was invented by German automobile engineer Heinz Kunert.

Etherloop is a hybrid technology combining aspects of Ethernet with other technologies to achieve a result not possible with either technology alone. EtherLoop was originally developed in the 1990s to allow high-speed data communication access to residential customers over standard twisted-pair telephone lines, also known as plain old telephone service (POTS). The technology development effort was begun at Northern Telecom in order to allow telephone companies to compete with the high-speed local data access then beginning to be offered by cable TV providers.
