Unless you're on the hype train "all things AI". It's always surprising how many real life problems do not necessarily need a solution based on the buzzwords du jour. All things blockchain, all things microservices, all things as-a-service, all those came and went, washing off the bubbles and leaving behind the (fewer) worthy pieces.
Buzzwords aside, I'm pretty sure the MTA's license recognition here is plain old ALPR, of the kind that's already been in use for municipal fare/toll enforcement for ~15 years.
