1. Understanding OBD2 and Mileage Verification

OBD2, or On-Board Diagnostics II, is a standardized system used in vehicles to monitor and diagnose various parameters, but it’s not the definitive solution for mileage verification. Let’s delve into what OBD2 is, its primary functions, and how it attempts to provide mileage data.

1.1 What is OBD2?

OBD2 is an automotive standard developed in the 1990s to provide real-time vehicle diagnostics. According to the Environmental Protection Agency (EPA), OBD2 was mandated in the United States for all cars and light trucks manufactured after 1996 to monitor emission-related components. The primary goal was to ensure vehicles meet emission standards and to provide technicians with a standardized way to diagnose issues.

1.2 Primary Functions of OBD2

The main functions of OBD2 include:

• Monitoring Emission Systems: OBD2 tracks the performance of emission-related components like the catalytic converter, oxygen sensors, and EGR (Exhaust Gas Recirculation) valve.
• Diagnosing Malfunctions: It detects malfunctions and stores diagnostic trouble codes (DTCs) that indicate the source of the problem.
• Providing Real-Time Data: OBD2 offers real-time data on various vehicle parameters, such as engine speed, coolant temperature, and fuel consumption.
• Standardizing Diagnostics: It provides a standardized interface for technicians to access vehicle data, making diagnostics more efficient and accurate.

1.3 How OBD2 Attempts to Provide Mileage Data

OBD2 devices estimate mileage by tracking vehicle speed and distance traveled over time. However, they do not directly read the odometer. Instead, they infer mileage based on trip data, which can lead to inaccuracies.

1.4 Limitations of OBD2 for Accurate Mileage Reading

Several limitations make OBD2 less than ideal for accurate mileage verification:

• Inaccurate Mileage Calculation: OBD2 calculates mileage based on speed and trip data, which can be imprecise. Factors like GPS inaccuracies and data sampling rates can affect the accuracy of the readings.
• Data Gaps: OBD2 devices may not capture all trips or data points, leading to incomplete mileage records.
• Tampering Risks: OBD2 devices can be tampered with, either intentionally or unintentionally, leading to incorrect mileage data.
• Compatibility Issues: Not all vehicles are fully compatible with OBD2 devices, and some may require additional adapters or modifications.
• Lack of Direct Odometer Access: OBD2 devices do not directly read the vehicle’s odometer, relying instead on calculated estimates.

2. The Problem with Relying on OBD2 for Mileage Verification

While OBD2 devices have their uses, they fall short when it comes to reliable mileage verification. Several issues make them less than ideal for businesses and individuals needing accurate mileage data.

2.1 Inaccurate and Incomplete Mileage Data

OBD2 devices do not provide a direct odometer reading. Instead, they calculate approximate mileage based on location or trip start and end points. This method introduces inaccuracies that can accumulate over time.

• Inferring Mileage: Calculating mileage based on location, speed, and trip data is inherently prone to errors. Small inaccuracies can lead to significant discrepancies, affecting auto insurance risk assessments and service recommendations.
• Data Comprehensiveness: Mobility businesses may struggle to obtain sufficient mileage data across their customer base, compromising the reliability and effectiveness of their services.

2.2 Risk of Unintentional Failure

Even when properly installed, OBD2 devices can fail due to various factors:

• Vehicle Reactions: Some vehicles may react poorly to OBD2 devices, triggering false alarms or draining the battery.
• Installation Issues: Drivers must install the device themselves, which can be challenging. A loose connection or accidental nudge can easily knock it out, rendering the device unreliable.
• Worst-Case Scenarios: If a dongle comes loose, it stops tracking miles without notifying the insurer, leading to inaccurate usage estimations and potential policy disruptions.

2.3 Software Incompatibility

OBD2 dongles often run on separate platforms that do not easily integrate with existing systems. This lack of integration can create extra work for businesses trying to sync mileage data with their current tools.

• Data Alignment Issues: Auto insurers may struggle to align dongle data with policy management systems, while repair shops face difficulties tracking mileage for service reminders.
• Integration Challenges: Road usage charge programs may encounter challenges integrating OBD2 data into their billing systems, adding complexity instead of streamlining operations.

2.4 Intentional Tampering

OBD2 devices are susceptible to intentional tampering, where drivers may unplug the device to avoid recording miles. This practice can lead to significant financial losses for businesses.

• Mileage Fraud: According to the National Insurance Crime Bureau (NICB), mileage fraud costs auto insurers billions of dollars annually. Over half of drivers misreport mileage, resulting in substantial losses.
• Service Reliability Issues: Mileage fraud can disrupt service reliability for maintenance schedules and billing processes.

2.5 Privacy Concerns

Consumers are increasingly concerned about data privacy, and OBD2 devices can raise red flags due to their constant tracking and potential data misuse.

• Lack of Transparency: Many drivers are uncomfortable with a device plugged into their car, constantly tracking their data without clear explanations of what information is collected, who has access to it, and how it is used.
• Explicit Data Consent: The lack of explicit data consent can erode trust between businesses and their customers.

2.6 High Expenses

The costs associated with OBD2 devices can quickly add up, making them a financially burdensome solution for mileage verification.

• Hardware Costs: New dongles can cost $50 to $60 per unit, while refurbished ones still cost around $17.
• Additional Fees: Businesses must pay ongoing subscription fees per vehicle, plus the logistics of distribution, fulfillment, and returns.
• Profitability Concerns: Instead of driving profitability, OBD2 dongles can become a financial burden compared to software-based alternatives.

3. Exploring Alternatives: Connected Car APIs

Given the limitations and problems associated with OBD2 devices, connected car APIs offer a more reliable, accurate, and cost-effective solution for mileage verification.

3.1 What is a Connected Car API?

A connected car API is a software interface that allows businesses to access vehicle data directly from the car manufacturer or a third-party platform. This data includes odometer readings, location, and other vehicle parameters.
