It depends how you look at it. Lots of car drivers do break the law, redesigning the street to discourage driving with high speed is a good thing when you care about the safety of the ppl. Not just to stop those with high speed, but also to reduce the avg speed to give drivers more time to react.
In this sense, if you put people safety as top concern, you help the masses(all the ppl are pedestrians at some point) by enforcing safe driving for the few that do drive with proper street design
You don't even need to make the punishment especially harsh.
What helps is to increase the likelihood you will actually get caught and face any consequence. It would be much better to reliably confiscate the cars of the people doing this than to randomly send a very small proportion of them to prison.
Not GP; but Scandinavia. I sadly had to give up my Norway residence attempt (by far the most appealing) for my current process in getting an Iceland residence permit, and ALL the times I've gone for tourism and culture - even for weeks at a time - it's not even close how much better it is. It has a culture you WANT to assimilate into, very high-trust and homogenous, almost all nation's pasts in Scandinavia are smooth enough to not disrupt modern society, very well-developed, tons of job opportunities in tech (and that's if you don't want to work remote), their structuration theory in politics is as reasonable as it is fair, lower populations, the list goes on.
