Dropping a single place in the current race isn't really a valid penalty though, is it? If it was any other time of the race, it'd be drive-through or it'd be a penalty in the next race, depending on the severity.
Don't think I've ever seen a penalty that resulted in just losing one spot, unless there was a massive gap between them and two spots back (or however it shakes out).
No, I don't think that's possible.
