I got my first 2 points in the door (driving 12 years) and an 80 euro fine for going 57km in a 50km zone (4mph over the limit) at 2 o'clock in the morning.

I think its really hard to keep the speed limit, i tried after i got the points but all i got was abuse, beeps, flashing lights and being overtaken by other drivers and even pulled in by the guards who thought i may have been drunk/or something wrong as he put it cause i was going so slow??
Now I find myself slowing down anytime i see a white van parked at the side of the road but putting the boot down as usual.
Do the points work? Do you find yourself constantly watching your speed and speed signs (if you are lucky to see one btw) for the fear of being caught? Do you vigoursly keep the speed limits on the various roads?
