Here in Denmark, weather i get stopped or not depends fully on the cop. Most cops dont care about it, when theres not razzias, but then when there are razzias, they have to stop every damn 2-wheeler they see, to check if its legal, no matter if its a bike, a scooter or a MC. :O
But the licence for riding the "little scooter" in Denmark is only around 10-20 euro, so thats not what hurts. What hurts, that the second time you get cought on an illigal scooter, they take it, and destroy it.
(that is, if 2 times in 3 years).
So, if i get stopped for riding derestricted, ill have to ride restricted for 3 years... That means that in reality, the prize for going too fast on an illigal scooter is: 1500 DKK, and the vario first time, and 1500 DKK and the scooter second time (which for me were 9000 this time). That rounds up to 17000 DKK, whitch is £1 545, $2954 or 2284 euro.
But i have to do it, because 18 MPH is really extreamely dangerous. The statistics say that 90 % of all danish scooters is illegal (speed), but only 10 % of all accidents is involving an illegal scooter. AND most of those accidents are cars making a right turn or coming from a sideroad without looking. That was what happened to me, when i crashed on the old agility (going 20 km/h, whitch is around 12 MPH.).
So the conclusion must be: The legislation sucks, and driving restricted is dangerous
