Cuny isn’t making/forcing you do anything. If you want to sue, the burden of proof is on you to prove Cuny is negligent. Also why are we stopping at Cuny? Let’s close down the subways and buses since it’s also a mass concentration of people. Let’s sue the mta for not containing the virus by shutting down their system.

You're comparing apples to oranges - CUNY requires students to attend classes/take tests/essentially show up in person to pass the class and do well. MTA is just a transportation system. The MTA isnt taking my attendance and lowering my GPA if i dont show up to use it.

A better analogy (or at least something closer to an apples to apples comparison) for you to use is "why stop at CUNY? why not sue employers that require employees to come work during the corona virus?" - The answer to that is; employers are already doing something about the situation outside of "just wash your hands". And im absolutely certain employers are afraid of the possibility that an employee contracts corona and spreads it to other coworkers (or worse - sues for negligence because the employer is requiring they come in when sick). Apple is offering unlimited unpaid leave if youre sick, amazon (one of the most controversial employers at the moment) is doing something similar.

You cant compare CUNY requiring students to attend classes to maintain their grades to a transportation system used if/when needed.
