In my country everyone is speeding as well, but speed limits are enforced primarily by the radar-cameras, not cops. So you just have to know location of those cameras (thanks, Waze) and slow down there.

I assumed that your concern was cops giving trouble just because they can, not for actual violations.

This is true where I live currently (Netherlands). Luckily, there are no silly cameras on my commute to and from work. :)

In America, cops generally will leave you alone unless you're actively breaking the law right in front of them. Most departments are understaffed already, especially in big cities. In Dallas, there were a couple of suburbs that were notorious for writing traffic tickets and in those areas, people would slow down. But those areas were wealthy and have low crime rates so the local police don't have much else to do.
