That's not half the battle. Undoing the zoning is 90% of the battle.

Cycle paths can be added at a step by step basis and keeping some gaps isn't an issue and if some paths aren't used much initially there isn't a big problem. Also sometime a single line painted on the road is enough for a start.

If businesses settle in dezoned area they need to attract an audience quickly, but the will be less attractive than the hyperstore or mall for car drivers and depend on a bunch of other businesses in walkable distance. Financing the period till it works can be tough and will cycle through a few businesses till a working mixture is established.

And even then: In the car centric land usage, distances are too far quickly for quickly walking over to the bakery for fetching bread for breakfast, 15 minutes as a guidance for reaching everyday shops, doctor offices, a bar, ... density has to be increased. But people won't give up their yards.

"Also sometime a single line painted on the road is enough for a start."

I have seldom seen this solution get respected by cars.

It is better than nothing, but it is a weak start, when the goal is save cycling.
