The released Dauphiné (Ysé Rieffel, 11 January 2025). Same article as Joanie. The three examples (birthday, gifts, journey) are these of the journalist, put up by Adèle. Distinct from Fabrice / François (MoneyVox, personal budget already in corpus). No mile or toll rate is published.

The prompt to customise
Trajectories: [départ, arrivée]. Km if known: [n]. Fuel price: [€/L]. Conso: [L/100 km].

Gasoline and toll estimates. If a tariff is not public, write "unverified". No toll price.

A generated calculation is not the actual cost. Cross-check gasoline and toll on a comparator or highway site before leaving, and do not paste any credit card or record into a general public account.
