IF the government did their job, it would be easy.
Catching speeders on the road is easy (trivially, you just need a radar gun, or an automated radar mounted in a car). Getting the police out of their offices and to actually do their job is hard (atleast here, in my country).
What I object to is complaining about "government" officials as if there is only one type.
In the US, regulators may not do their jobs because it is can be extremely financially advantageous to look the other way. But the system of legalized bribery is in place because of deliberate choices by the system architects who made the problem much worse than it had to be.
The US government has been sabotaged. Blame the saboteurs.
But that's literally what you said?
"This is easily fixed by governments doing their jobs."
