Others have already pointed out that you, which used to be exclusively plural, still takes plural verb forms and nobody gets confused. I'll add that this phenomenon is not restricted to English. On, in French, is traditionally a singular indefinite-person pronoun, mostly equivalent to the pronoun "one" in English (which sounds a bit archaic/formal now, so maybe a better translation is "people in general"). It takes singular third person verb conjugations. However, nowadays, on has almost completely replaced nous (meaning "we") as a subject pronoun in informal, colloquial speech. But its conjugation is still third-person singular. "We saw each other" is thus translated in formal speech or writing as "Nous nous sommes vus", and in colloquial speech as "On s'est vu".
