Let's concider this. A truck driver loses his license for a month due to repeat offences. He earns his living by driving so this is a blow to his income. In fact in Finland people who drive for a living have been struggling to change the laws so that they would be exempt for losing their license due to minor offenses, even if those are numerous.
I think that should be looked at like a doctor losing their license to practice medicine. If your job requires you to drive, then the expectations on you to obey traffic laws should be greater, not lesser.
Or, at least, that should've been the case to start with. At this point, though, if the culture of "you must obey these laws or the consequences are terrible" doesn't already exist, it will not appear overnight. Lots of people losing their livelihood is not just something to shrug off and say, "oh well, these things happen". And if the enforcement of traffic laws is not uniform but circumstantial (Get the cop who's in a bad mood and they'll enforce laws that they usually don't, etc.) it compounds the problem. I don't know if that's a problem in Finland, it certainly is here.
Damn you, complex issues.
