Mate that is among the worst offences on the road in my view. It amazes me how many people are oblivious to any one eslse on the road, and drive well under the speed limit everywhere. If its 100, they drive 80-90. If its 80, they drive 60. If its 60, they drive 40-50.
And get this, there is another class of slow annoying driver. Having held up the traffic, by driving slow, until there is 20 vehichles built up behind them, they come onto an overtaking section. You think, Great! we will get past! No Way! these turkeys now speed up by 20 kms an hour! and minimise how many peole can get past! you have to go like the clappers to get past them. Now that my friend, is way up there in the worst driving habits of all time!!
