Information about cars:

Cars are typically fitted with multiple types of lights, these are used to illuminate the way so that the vehicle can be used at night, to indicate turn intentions of the driver, and to display that the vehicle is braking. Additionally courtesy lights are usually fitted for the passengers.

The weight of a car influences fuel consumption and performance, with more weight resulting in increased fuel consumption and decreased performance. According to research conducted by Julian Allwood of the University of Cambridge, global energy use could be heavily reduced by using lighter cars, and an average weight of 500 kg has been said to be well achievable.

In some competitions such as the Shell Eco Marathon, average car weights of 45 kg have also been achieved. These cars are only single-seaters (still falling within the definition of a car, although 4-seater cars are more common), but they nevertheless demonstrate the amount by which car weights could still be reduced, and the subsequent lower fuel use (i.e. up to a fuel use of 2560 km/l).

Most cars are designed to carry multiple occupants, often with four or five seats. Full-size cars and large sport utility vehicles can often carry six, seven, or more occupants depending on the arrangement of the seats. In the other hand, sports cars are most often designed with only two seats. The differing needs for passenger capacity and their luggage or cargo space has resulted in the availability of a large variety of body styles to meet individual consumer requirements that include, among others, the sedan/saloon, hatchback, station wagon/estate, and minivan.

Road traffic accidents are the largest cause of injury-related deaths worldwide. Mary Ward became one of the first documented car fatalities in 1869 in Parsonstown, Ireland, and Henry Bliss one of the United States' first pedestrian car casualties in 1899 in New York City. There are now standard tests for safety in new cars, such as the EuroNCAP and the US NCAP tests, and insurance-industry-backed tests by the Insurance Institute for Highway Safety (IIHS).

Car propulsion technologies that are under development include gasoline/electric and plug-in hybrids, battery electric vehicles, hydrogen cars, biofuels, and various alternative fuels. Research into future alternative forms of power include the development of fuel cells, Homogeneous Charge Compression Ignition (HCCI), Stirling engines, and even using the stored energy of compressed air or liquid nitrogen.

New materials which may replace steel car bodies include duralumin, fiberglass, carbon fiber, and carbon nanotubes.

Telematics technology is allowing more and more people to share cars, on a pay-as-you-go basis, through car share and carpool schemes.
