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.
