When to Rent vs. When to Take Transit
Rental car total cost = (daily rate ร days) + (miles รท MPG ร gas price). Transit total cost = one-way fare ร 2 (round-trip) ร number of travelers. Because the rental car's base cost is fixed regardless of group size, adding more people to the car lowers the per-person cost dramatically.
Cost per person is usually the fairest comparison. For solo or two-person trips to transit-friendly cities, public transport typically wins. For groups of 3+ heading to car-dependent destinations, renting often comes out ahead โ especially once you factor in the flexibility of not being tied to schedules.
