> in my country (the netherlands) i have seen people stop at stop signs at times when there is very, very little traffic (04:00 at night).

This is also normal in the US, despite what a few commenters on HN may have you believe. Hell, if anything, regular people out and about at 4am are better about following the basic laws, because you stand out a lot more when you flout them, and in the wee hours of the night the proportion of drunk drivers is far higher and so cops are looking for it.
