Tradie in a hurry to get to work with little or no regard for cyclist safety

Cycling south on Logan Road, Innes Park when overtaken by a silver Isuzu D-Max Dual Cab towing a large twin axle trailer. This area of road has considerable housing development including the new Drift Retirement Village under construction. The road is relatively narrow in poor condition and without side markings. I was approaching another cyclist and slowed as I knew that there was a vehicle approaching from the rear (the Isuzu). It overtook me with no regard to the prescribed one metre rule and cut in close due to the trailer it was towing. This then put it between me and the other cyclist. It then overtook the other cyclist and with a couple hundred metres turned into the workplace it was going too. Saved him a few seconds on the work clock! Seems it was more important for him to get to work then any consideration of other road users. It would have been safer and more considerate to stay behind and turn in after we had crossed the entrance to their worksite.
