This wasnt my mistake this time, but gave us all a really good laugh. About 10 years ago we were towing an enclosed racecar trailer back to Sydney from Gunnedah. With my mates Hilux we sat on a confortable 90kmh on the flat and up hills as well. After a while we had a bloke towing what looked like a fancy new bowrider type sitting about 6 inches off the back of our trailer, he would flash his lights and get all agitated on the flat sections but when it came to dual lanes going up hill he wouldnt be able to maintain 90 and would pull alongside and then fallback again. After a few kilometers of this we decided just do drop back and let him past before he killed someone. As he passed he gave us the bird with a few choice words and tried to take off, it was then we noticed his ouboard still down and grinding away on the road everytime he hit a bump. When we pulled up at some lights a bit further down the track, we just gave him a friendly wave and kept going!!
