Obviously, depends on the road and conditions at the time, but this does drive me mad
My route to work is along a nice straight, wide NSL road with open fields either side, good visibility, yet every Monday, Wednesday and Friday I get stuck behind the same person trundling along at 25mph with huge queues behind. Sometimes they creep up to 30mph, then we all get excited, but then the brakes go on and it's back down to 25mph. You can't over take as the road is busy so no break in the oncoming traffic
I can understand people not wanting to do 60, but less than half the speed limit?
I can't leave any earlier as I have to drop my daughter to school, so it makes it a bit tight for me getting to work on time.
Saying that though, on Friday morning I saw they'd been pulled over by the police, hopefully they've been spoken to. I had the morning off work today.
One of my neighbours does 40mph regardless of the speed limit, she's been done for speeding in a 30 twice, but thinks shes a perfect driver as she never goes above 40.
