I'd like a cop show that does this but it's conventional AI and it confidently makes up a licence plate but the cops take it seriously and commit to tracking it down.

And there should be maybe a few instances of people trying to explain in various ways "this is AI, the letters and numbers are made up, that car has like a 0.000001% chance of having had that specific random licence plate, please, stop looking for it, you're being dumb" then the cops pretend like they understood and had an interesting conversation then they go right back to tracking the generated license plate to the best of their ability. A bit like cops who go on to order polygraphs the day after their nephew passionately tried to explain the insanity of the whole "lie detector" charade.
