I'm in Canada, so it's possible that my experience differs. I will edit the post to clarify that I'm talking about arterial roads and highways though, not residential streets. Most main non-highway roads here still have limits of 50km/h (30mph), with the average speed ranging around 20% higher than that. Most highways have limits of 80km/h (50mph), with average speeds perhaps 10-20% higher, and IMO safe speeds in good conditions often 50% higher.
