Hilarious! If i didnt already have too many projects and hobbies, this is the kind of thing i'd do.

Maybe not a speed leaderboard, that just seems like a challenge to choon heads. But perhaps a "violation count". Also toss in a dB meter for loud exhaust (again dont make it a contest).

Edge compute with alpr/face/gait/whatever object detection at the camera is basically solved. Genie is out of the bottle. I think the most fruitful line of resistance is to regulate what can be done with that data once it leaves the device.
