Your speedometer! It tells you how fast you are going at that instant.
All different types of devices are used to measure instantaneous velocity including chronographs, lasers, and radars.
It reads instantaneous speed, and tells you nothing about average speed.
Instantaneous speed is the speed of an object at a specific moment in time, while speed refers to the average rate at which an object covers distance over a period of time. Instantaneous speed gives the speed at a precise instant, whereas speed provides an overall measure of how fast an object is moving.
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
No instantaneous speed is not final speed.
Instantaneous speed depends on the distance traveled by an object and the time it takes to cover that distance. It is a measure of how fast an object is moving at a specific moment in time.

Instantaneous Speed.
To measure instantaneous speed, you would typically need a device that can measure time accurately, such as a stopwatch or a timer, along with a distance-measuring tool like a meter stick, odometer, or GPS device. By recording the time taken to cover a specific distance, you can calculate the instantaneous speed at a particular moment.
To be pedantic... In a car with a digital speedometer, speed is NOT instantaneous in the sense that it is a measure of distance per unit time. It does this by measuring a change in distance over a very short period of time to *approximate* the instantaneous speed. If the time period is a small fraction of a second you wouldn't know the difference! For older cars with analog speedometers the speed is instantaneous as it directly translates the speed at which your wheels are turning.
Instantaneous speed cannot be measured because it is a theoretical construct. It is the speed that an object has at one particular moment, but measuring the speed of an object necessarily involves several moments so you can only measure the speed over some finite amount of time.
Instantaneous speed:- It is the rate of change of position with respect to time,at that instant. Average speed:-Average speed is defined as the total path length travelled divided by the total time interval.
Instantaneous speed is the speed of a body at any one instant. There is really no such thing as the instantaneous speed, it is merely the average speed over a very short space of time.
