FWIW I think adding more cameras and monitoring equipment would have a strong incentive since it could still increase the total number of tickets given out.

Either way the government is not purely incentivized to increase funds. Standard fines for traffic violations are changed up or down all the time. Sometimes cities decide their current traffic enforcement is too burdensome and they cut back on tickets. There could be political actors which have incentives to improve it. Whether or not it will ever happen is not clear but I dont think its impossible by any means.
