> The only person this really benefits is new users to the system that haven't figured out how to get a transit card yet.
In many transit systems, that's millions of people per year: Tourists, occasional riders that would just forget the pass at home if they're not using it regularly etc.

There's theoretically ways to preferentially pick a given type of card, but it's quite hard and unreliable to implement, so I guess that rather than promising something they can't reliably deliver (and slowing things down in the process), transit systems just pick the first card.
It is slightly inconvenient for transit-pass-only users, but I do also see the huge benefits for the transit system and its users in aggregate.
