Regardless, humans are social and territorial creatures. Occasional exchanges are natural and should be expected. In the end its just a pissing match which very rarely progresses to anything further. When given the chance to induce real physical injury to a complete stranger - most psychologicaly healthy indivuals would back down.
To mix it up from time to time, I like to react in unexpected (but generally safe) ways. Maybe I should practice a falling in a convincing manner - it would be an interesting social experiment to see how quickly some change their attitudes.
Threatening drivers, to me, are a helpful reminder that all vehicular traffic is dangerous - regardless of their intent. Who is more dangerous on the road - the driver that notices you or the one that does not?
I like the camera idea, perhaps I will carry a small digital in my pocket. Instead of "discussing" the situation with the driver, take a picture of them and their car.
