Much of the instrumentation has been computerized. Lights and alarms may indicate low fuel, outside light malfunction, improperly closed doors, or unfastened seat belts. Some automobiles have microcomputer instrumentation, including a bar chart fuel gauge, digital speedometer, and message center. The center can provide information about numerous mechanical conditions and can tell how many miles remain to a particular destination. Some vehicles use a computer chip to determine fuel consumption on both an overall average and an instantaneous basis.
Many cars have bucket seats in front.
These are individual rounded seats, set close to the floor. Other automobile interior features include heaters and air conditioners, power-operated windows and seats, and radios and audio tape players. Bumpers, Lights, and Accessories-Bumpers that absorb impact from minor collisions at low speeds, therefore protecting a car's body from damage, are standard on many automobiles. An automobile's lighting system includes dim and bright headlights, parking lights, turn signals, tail lights, backup lights, stoplights, ceiling lights, and dashboard lights. Some cars have map lights, floor lights, and cornering lights, or sidelights, that switch on automatically when the car is turned.
