I can't believe you think you're in the right. You must keep left unless overtaking on freeways. What planet have you been living if you don't know that?
I do a lot of freeway kms, and there is always some d***head hogging the right lane, completely oblivious to what's going on around him/her, impeding the faster traffic flow and therefore potentially causing dangerous situations. Standard response is "i'm going fast enough, no one passes me" or I passed a car a few minutes ago. How stupid.
I've driven in Euro countries with higher speed limits, and they have very courteous and safe road manners on the motorways. Come back here and see how some morons are on the fwys, makes you wanna cringe.
Anyway, while I stongly disagree with the current overactive speed camera situation here in Vic, I fully agree that they enforce this right lane rule to the letter.
BTW, if I was the cop, I would have also locked you up for being a smart a**e.
Drive safe
