Dedicated short-range communications (DSRC) is a technology for direct wireless exchange of vehicle-to-everything (V2X) and other intelligent transportation systems (ITS) data between vehicles, other road users (pedestrians, cyclists, etc.), and roadside infrastructure (traffic signals, electronic message signs, etc.).

An electronic odometer (below the speedometer) with digital display showing 91,308 miles (146,946 km) An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two (electromechanical).
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity.

Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once an obstacle is detected, the sensor continues to signal the presence of the obstacle even if the vehicle momentarily stops. If the vehicle then resumes moving backwards the alarm signal becomes louder as the obstacle is approached.

A hubometer (from hub, center of a wheel; -ometer, measure of) or hubodometer, is a device mounted on the axle of any land vehicle to measure the distance traveled by a vehicle based on the rotations of the wheel hub. The whole device rotates with the wheel, except for an eccentrically mounted weight on an internal shaft.
