I remember reading about a particular speeding camera that is actually turned off the majority of the time due to the sheer number of speeding tickets that are produced from it alone. It's so much that it clogs up the entire system so they just gave up and turned it off for like 2/3rd of the time so the people processing those tickets have time to work on other cameras.

Raising the fines is good and all (rather it really should be done), but I think the entire ticketing system needs to be overhauled as well so that it's far more streamlined to handle massive loads without hiring thousands of more people to brute force the problem.

The number of people who brag about their fines is staggering, treating them like badges of honor. If you check out automotive forums, you'll see it all the time, with people trading tips on how to push the limits of the demerit system to avoid having their license revoked without actually fixing their habits. There's even tips on how to legally obscure your license plate so you can't get caught on speed cameras.

Also regarding those highway speeding cameras, normal speeding cameras just take two pictures and measure how far the vehicle has moved during that time. Though if you just equip the camera with a doppler radar, you can just directly measure the speed that way.
