Would you happend to have any grey poupon?

I honked at a car straying into my lane after a turn today and it swerved back into line. Even a car has body language and this one said *flustered*. Now that the honk is almost universally understood as 'fuck you', I only wish there was a friendlier way to alert the other car, as I didn't mean to be mean. Perhaps a 'ding ding' sound, or a quick 'quack' like when you rub a Mac the wrong way. Of course, I've always been a proponent of an option in cars to have a mic inside attached to a loudspeaker on the outside for such purposes, and of course the instances when a 'fuck you' needs to be delivered and understood unambiguously.
