The card system would probably be best where just buy a card and load it up at a kiosk. There would still be potential security vulnerabilities if you were allow someone to "anonymously "view that transaction. Or allow someone to view the card trips. Which would just be logged with its number.
And I’m just more so talking about the current system they have in place. I’m not sure what else they could do utilizing their current system except for forcing some kind of account
Every city had a fine system using cash/coins or cards you could fund at a kiosk by cash coin or card. Those cards were anonymous.
Now everyone has to be fancy and link credit cards and phones to accounts for every activity of daily life.

It would be trivially easy to add privacy any number of ways if they didn’t insist on tracking the users and logging that info.
They could even track it and just not make it available by web. Or require 2FA. Not exactly a nation-state level attack being described here.
People have just become accustomed to not caring about privacy and so that’s what we get.
