odometer

Vehicle's odometer reading, in kilometers

High-Level Explanation

How far the vehicle has driven since it was built, in kilometers

Enables

odometer exists for all Tesla vehicles, but not all other vehicles. odometer enables determination of distance travelled, assists in identifying the start and end of trips (based on odometer ceasing to increment), and serves as a data point relevant for vehicle valuation, among other possible uses.

Note that because odometer is not available for every vehicle, sometimes the haversine distance between sucessive points must be used to estimate things like distance travelled (though the haversine distance would underestimate distance travelled)

Known Quirks

There are sometimes nonsensical values in the odometer signal values, sometimes due to a different vehicle reporting data for the same subject value.

One method to deal with these values is to remove records where odometer decrements rather than increments. Additionally, records where the odometer increases so much in a short time that the speed travelled would not be physically possible can be removed, similar to removing records where (the haversine distance between records / time between records) is results in a speed that is physically impossible, as in Code Appendix.
