autant …
Autant attendre.
But as long as you've fixed a supper, we may as well eat it.
Mais puisque tu as préparé le dîner, autant le manger.
— Psycho (1960)
We may as well stay here till the weather improves.
Autant rester ici jusqu’à ce que le temps s’améliore.
Autant commencer tout de suite.
We've finished the work, so we may as well go home.
Nous avons terminé le travail, alors autant rentrer chez nous.
