Are there any paved trails they can learn on? Rails-to-trails can be great, as they're naturally flat and straight, if there are any of those near you.

Dutchie here, we have the opposite super power. Bikes are everywhere, we are used to them. Most of the times in urban settings the bike is the best option.

We also get buffs to perception. Being used to bikes means noticing them. 'the Dutch reach', where you open the door with your opposite hand, so you watch out for bikes, is a lie. We don't do that, we've gotten used to looking for them, because everybody knows what's it like to actually be on a bike themselves.

Are you in one of those north American developments with long straight multiline roads without proper sidewalks?

If so, something like this doesn't exist here at all. The smaller roads are not really suitable for high speed driving, and there's not much traffic. The main roads all have wide foot and bike paths on both sides next to them - so only thing you need to know is how to safely cross a road.

In addition to that there are lot of small pedestrian/cycle only paths as shortcuts between parts of the city.
