Cars are typically fitted with multiple types of lights. These include headlights, which are used to illuminate the way ahead so that the vehicle can be used at night, brake lights to indicate when the brakes are applied, turning lights to indicate which way the driver is turning and white-colored reverse lights. Interior lights on the ceiling of the car are usually fitted for the driver and passengers. The weight of a car influences fuel consumption and performance, with more weight resulting in increased fuel consumption and decreased performance. Research has proved that global energy use could be heavily reduced by using lighter cars. Most cars are designed to carry more than one person, often with five seats. Cars with five seats typically seat two passengers in the front and three in the rear. Larger cars can often carry seven people. On the other hand, sports cars are usually designed with only two seats. The differing needs for passenger capacity and their luggage space have resulted in the availability of different car types that include the sedan, hatchback, station wagon and minivan. Road traffic accidents are the largest cause of injury-related deaths worldwide. Road traffic is becoming ever safer due to new safety features in cars such as seat belts and airbags and on roads due to new safety features like speed bumps. While there are different types of fuel that may power cars, most rely on petrol or diesel. The average vehicle will emit 10,180 grams of carbon dioxide. Many governments are using road taxes to influence vehicle purchase decisions, with a low CO2 figure often resulting in reduced taxation. Growth in the popularity of vehicles and commuting has led to traffic congestion.
