Small group discounts and fare credits would be such game changers. FWIW, if you have kids 5-11, they use the half price discounted fare (but are free on weekends/holidays the night before until the early morning after), and 0-4 are always free. Seniors 62+ and disabled also get that discount, which really can knock family costs down.

With adults, I’ve use the 10-trip (for bus) and 20-trip 20% discount packs as group pseudo-discounts. Groups of 8+ have official 25% discounts, but they’re annoying to file for.

Sometimes a car just is better if you’re filling it up, have people with mobility problems, or have inconvenient endpoints (don’t forget maintenance and depreciation). Options are good to have.
