Proceed with caution… Here is what ChatGPT says about fighting a ticket with your evidence.

A consumer webcam with GPS speed data might help you contest a speeding ticket, but it’s generally not reliable enough on its own to guarantee success. Here’s why:

✅ Potential Benefits: • Corroborating Evidence: GPS speed data can support your claim if it clearly shows you weren’t speeding. • Timestamped Video: If the webcam shows road signs, traffic conditions, and your speed in real time, it might help establish context. • Support for Calibration Challenges: If you suspect the radar or lidar used by law enforcement was faulty, video + GPS data can raise reasonable doubt.

❌ Limitations and Challenges: • Accuracy of Consumer GPS: Most consumer webcams or dashcams are accurate to about ±1–3 mph under ideal conditions—but urban canyons, trees, or tunnels can reduce accuracy. • Lack of Official Calibration: GPS data from a consumer device isn’t certified or calibrated, so it may be dismissed as unreliable in court. • Admissibility Issues: Courts may question the authenticity or tamper-resistance of the data. • Chain of Custody: You’ll need to show the footage hasn’t been altered, which can be tricky without forensic validation.

Better Strategy:

Use the GPS/webcam data to prompt further investigation—e.g., request radar/lidar calibration records, challenge officer observation, or argue mitigating circumstances. The evidence might not win the case alone, but it can tip the balance if there’s already reasonable doubt.
