I'm Dutch, you're almost right. Most people won't even reach 15 mph. Speeds around 10 mph are more common.
Funny thing: wearing helmets is much more common in Germany. If you see adult cyclists wearing a helmets on upright bikes they'll speak German most of the time :)
Generally I wear a helmet if I'll be doing more than 15 mph, or riding through a city.
