Which is more accurate car Speedo or sat nav?

Are digital speedometers better?
Also, digital speedometers do display the speed based on the sensor data in actual digits, but there is a lag between what is displayed depending on how fast the data is read on the sensor and how fast the screen refreshes. Despite this, digital displays can be more precise especially when it comes to measuring speed.

Is a speedometer analog or digital?
A speedometer that shows a car’s speed by means of a dial is an analog device. The hand on that dial moves smoothly around the dial and can take any value that the car’s engine can create. In a digital device, values are represented by numbers and therefore do not have the variability of analog devices.
