Pretty simple fix: require more data to look up a citation, like the number, issue date and plate/VIN (this is how my city does it). Technically doesn't make the scraping impossible if you wanna try every permutation of a license plate, but makes it mostly infeasible.

Currently it just requires the sequential citation number [1], which is how the data is being scraped so easily.
