Me. Nah not really but there are a lot of ignorant people out there.
I will sit in the right lane doing the limit - 5 kms over. This is not illegal, im doing the speed limit. Yet people cane it up my ass (to make me go faster). So Fu(k them, i slow down. Just because "im in the R" or any other bullcrap reason for speeding, why the fu(k would i move out the way for you?!?
As for the type of car that do this, mostly work vans and 4wd's.
Gotta love the look on peoples faces when they push their way into the left to get past you but they cant cos the traffic flow is to slow
