Now come to chicago and drive around here for awhile without knowledge of the local speed traps. That was the premise I posted, how about you pay attention to the thread and show some reading comprehension skills?
Extremely revelant. I drive 5-10mph under the grossly underposted speed limits late on friday and saturday nights especially in areas I am less familiar with and anywhere I know cops hide running radar. The reason is that here in the USA, speed limits rise and fall on the same road at random. One could be driving along at a normal 50mph on a 40mph posted road, and with no change in the road at all the speed limit could suddenly drop to 30mph for no apparent reason.
Given that your nation is becoming addicted to the revenue grab in short order, the same tactics will likely show up if they haven't already.
If it isn't gone, I really should go and get a picture of something I saw a couple weeks ago. A 40mph speed limit sign (on a road where I have been rutinely tailgated while driving 40mph) with a 25mph work zone speed limit sign about 15 feet behind it.
