>vinegar will rust all the metal it touches if you just leave it there and don’t wipe it off

This is true, but only because the acetic acid in the vinegar can remove any initial oxidized layers to help rust form deeper within the metal. You would need to leave at least a puddle of vinegar on a metal to see an increase in corrosion. The amount of evaporated vinegar from an open container is not going to be significant enough to cause corrosion. Moreover, there isn't going to be much exposed metal inside your car for the acetic acid to land on anyway. It wouldn't be any more corrosion than you driving through a rainstorm.
