Legal notice
Contributions are capped at the lower of HMRC 45p/mile or an itemised calculation (fuel + wear‑and‑tear p/mile + parking/tolls).
Drivers may not receive more than cost recovery; no surge/pricing for profit.
Example London ↔ Manchester: 200 miles × £0.45 = £90 cap → ~£30/seat with 3 passengers, plus any parking/tolls split.
