My pet hate is people who cant stick to a constant speed, I cruise at about 75 to and from work and overtake the same car about 5 times

Alot of the time people think if they pull into the middle/left hand lane then they wont get back out for overtaking, these are usually poor drivers with no sense of awarenss and poor judgment of speed and distance.

Is there a reason motorway driving isnt part of learning to drive? how can proving you can potter around town at 30mph qualify you to drive at 70+ in busy 3 lane traffic?
