Yep, does work...
Saw it on the news earlier; there really was no need for him to drop one side onto the dirt (the Pajero/Shogun? before passed fine)... Not sure if the truck was a B-Double, oversize (possibly, but not a big oversize as no pilot vehcile) or a road train (and what the trailers were) but a road train at 100kmh can get a bit of swing on the rearmost trailer, so that can influence things... the Disco could have slowed down in the time and then moved over, or used UHF ch40 to talk to the truckie - most truckies will monitor that and 18 - to see what the driver wanted the driver to do.
