We have a general problem of de-skilling which means many drivers don't/won't overtake, and don't leave return gaps either. The roads are also much busier, so I think we need a new definition of anti-social speed. If you're doing 35 on an NSL road with a long queue behind you (and conditions are good), you're driving at an anti-social speed. Either learn to drive at a reasonable speed, or get off the roads.
The roads are there for all users, not just car drivers who have a theoretical "right" to travel at 60 on roads that do not have a specific limit. Dog walkers, pedestrians, horse riders, animals and tractor drivers also deserve consideration.
The speed limit is a maximum, not a target, and the slow driver ahead may be aware of some risk you have either not noticed or have ignored. Either way they do have a right to be there.
