YES, and,
It is not just the legal consequence of the fines for speeding. When you get a ticket, you get points against your license, and end up paying more in insurance, often for up to seven years.
If they want actual automated enforcement, make it a toll, like a congestion fee.
It is free to drive at the basic speed (e.g., 65mph on the highway), but higher speeds cost more, up to a limit where it becomes a criminal offense requiring an actual Law Enforcement professional involved. The speeds could even be adjusted for time of day, weather, and traffic. So, you want to go faster, stay in the fast lane, and pay $X/mph/mile.
With the average speeds on highways often over 75MPH, collecting $0.10/mph/mile over the limit would result in good revenues.
