I've had zero tickets for speeding so far. Some for parking where I shouldnt, but never payed them.
However they've gone nuts here in Spain with traffic regulations. They want to "upgrade" traffic offences to criminalism, which means that if you go 180 km/h in a 120km/h motorway and you get caught, you could go to jail instead of getting points out of your license.
I must say that, overall, people have lifted off their throttle pedals, so fear does work, sadly.
