A dead reckoning sensor takes a known starting position and detects motion to estimate the new position. This is useful when new reference points are hard to come by.

Imagine you start to walk through the woods. You know where you start, you know how fast you are walking and you know the direction (from a compas for example). Now you can look at your map and estimate where you are. It wont be exact but its allot better than saying you are in the forest between two trees.

A mouse can work to detect motion and direction and adequate software will tell make it into a dead reckoning sensor but as mpilchfamily points out, you need to stay close to a surface for the mouse to work and the speed can probably not be too high.

If you want to use it on a full sized car I suggest you use a diferent kind of sensor than an optical mouse.

It can be used in any application you want. Though one made from a mouse has to stay very close to the ground and won't be very accurate and may not be able to keep up with a car. If you want a system for a car then you will have to scale it up a bit. But rather then use an unreliable system like that on a car why not use GPS?
