MTA expands AI surveillance system to detect fare evasion, raising privacy concerns

The MTA is using AI software to monitor fare evasion at subway stations in NYC.
The system is currently active at 7 stations and will expand to around two dozen more this year.
The MTA says the AI is for research and counting fare evaders, not sharing data with police.
Privacy groups worry about increased surveillance and potential misuse of the technology.
It's unclear if the AI can identify riders' faces; the MTA says it won't share data with police.
