odometers
An odometer is a device used in vehicles to measure the distance traveled. It typically displays the total miles or kilometers driven since the vehicle was manufactured. Odometers can be mechanical or digital, with mechanical versions using gears and cables, while digital ones rely on electronic sensors.
Most modern vehicles have an odometer as part of the dashboard, allowing drivers to monitor their travel distance easily. Some odometers also feature a trip function, which can be reset to track the distance of individual journeys. Accurate distance measurement is essential for maintenance and fuel efficiency.
