You may be wondering why the odometer reading in your vehicle differs from the distance calculated by an online mapping provider. The answer is simple: although vehicle odometer readings are close to the actual mileage traveled, they are not precise.
Surprising to many, there is no federal law that regulates odometer accuracy, only guidelines by The Society of Automotive Engineers that allow for a margin of error of plus or minus four percent. A FOX19 report on odometer readings found that four vehicles of different makes all registered inaccurate readings. Some readings overshot the mileage driven, while others under reported the mileage driven. Even a variance of twenty feet per mile driven could result in a discrepancy of over five-hundred miles over the vehicle’s lifetime.
How do I prevent this?
Always keep your tires inflated, check your tire tread, and follow regular maintenance for your vehicle. Aftermarket modifications such as custom wheels can also have an effect on the calculated distance.
However, there is no way to ensure that your car’s odometer reading is one hundred percent accurate without spending a lot of money on installing a module in your car. We recommend you keep an eye on your odometer reading and use it as a close, but not precise, look at your driving history.
How does this affect my reimbursement?
For those who use GPS signals to pin-point their location throughout the day, the distance traveled is computed through our mapping provider. This distance appears in your Motus mileage log and is what your monthly reimbursement is based on.
In the end, there can be a small variance between the mileage recorded on your vehicle’s odometer reading and the route distance calculated through mapping software. While both methods aren’t one hundred percent accurate, they should be relatively similar. If you do have concerns, cross reference your vehicle readings with your app readings as well as an external source like MapQuest or Google Maps.
