Tests on dash cam and racing game video recordings

Would be good to try this method on more dash cam and racing game videos from youtube, where the actual speed is displayed on screen.

See here a demo video from a racing game, where I provide a simple OCR to read the speed displayed on screen:

OSSDC PS3/PS4 Simulator - Speed Recognizer demo - GT5 PS3 60fps - Nurburgring https://youtu.be/0denLQRRP94

The source code is here, it can be used to easily validate the predicted speed:
