Translate the following English sentence to French:
"It would be a serious matter if every non-European company were to learn to use Europe as a bus where you do not have to pay for the ticket, you do not have to pay for cooperation, you benefit from using the facility and you leave without being accountable to anyone."
La situation serait grave si toutes les entreprises non européennes apprenaient de facto à se servir de l'Europe comme d'un autobus : on paie le billet, on ne paie pas la collaboration, on encaisse pour avoir utilisé ce moyen de transport et on s'en va sans rendre de comptes à personne.
