You'll remember that for a while...
Some years back I saw something similar on the Mount Lindesay Highway (90kph).
Falcon slowing to turn off to the right (on a road doesn't even even exist anymore), and a ute following behind obviously wasnt watching and run straight up the back at full pelt. Tray full of tools and parts goes flying as the ute bounces off to the left, Falcon all bent up and now sitting in the oncoming lane.
Both of them hop out of their vehicles having a minor freak out. I drove the Falcon off the road (well, kinda... the arse end bounced half a dozen inches off the ground each wheel rotation so it more hopped than drove) and helped old mate push his ute off the road and get all his bits off the highway. Traffic was banking up pretty quick and you could hear the hard braking going on so was only a matter of time before another stack happened.
About a dozen other cars had pulled up by then so I just left contact details and headed off. Always wondered how that played out.
