Nope. I travel in the lefthand lane. Only go into the right one when overtaking. Those are the rules I believe
I'm not yer Sunday driver, used to do 50 - 80,000 a year. Only copped 2 speeding fines in 30 years, and they were because of inattention. Only ever dented 2 vehicles ( and I've had about 12 in Aus including company ones). The speed limit is the max you are allowed to do, nothing says you have to. Common sense (not so common) says you drive at the safest speed conditions and your vehicle allows. In the UK you can be done for driving dangerously and be well under the speed limit. Should be universal. Speed, in the wrong place, DOES kill.
