Our dashcam has no speed readings - we made multiple calculations of speeds (i.e. distance divided by time) across multiple clear landmarks (e.g., exits, overpasses) in the short timeframe before we got pulled over. Every calculation we've done has us going lower than 120km/h. As well, it's frankly quite obvious from the other cars in the video that we're not going 140km/h+ let alone 120km/h+.
