I'm very sorry to hear of your experience. I've also encountered some aggressive drivers in Canberra but nothing like that. I think fortunately the percentage of total idiots on the road is actually quite low - they just stand out like sore thumbs. Try to imagine if even 1% of drivers were like that dropkick; there would be an accident every km.
Up until recently I drove an old diesel landcruiser. On roads with no passing opportunities I would often develop quite a 'following'. The great majority of drivers were only mildly irritated by my presence and managed to behave themselves. (I, in turn, took every chance to let them pass, sometimes pulling over for a minute to let them through). However I did get the occassional tailgaiter (sometimes I couldn't see their bonnet). In that case I simply lifted my right foot and dropped 10km/h, if that didn't work I'd drop another 10. I was quite willing to come to a stop and engage reverse if that is what it took to get my point across but I never had to go that far before the message got through. Of course I had the advantage that no one would want to run into that beast.
Perhaps you should move down here. Wollongong drivers are the nicest people in the world
, perhaps it's all that nice soothing cloud
