"More than half of Helsinki’s streets now have speed limits of 30 km/h."

This is the only secret.

People over speeding is what kills.

For dumb Americans like me - that 18.641 miles/hr.

I agree, but if the streets are set up accordingly, it's about as fast as you'd normally want to drive anyway.

For the standard US road with 12-foot-wide lanes and generally straight-ahead routes, 20mph does feel very slow. I've driven on some roads though where narrower lanes, winding paths, and other "traffic calming" features contribute to a sense that 20mph is a reasonable speed.

Yes narrower lanes is "traffic calming" in itself. Residential roads and city streeets should have different lanes than highways.
