Earlier quoted context omitted.
Bike lanes in neighborhoods aren't as necessary as the traffic is slow and there isn't much in neighborhoods to bike to - grocery stores, jobs, and so on. This is pretty much a recipe for failure. Instead, we need major corridors to have safe bike lanes. The major route between residential and business areas is a good place to start since the scariest traffic is there.
If there's no shops or jobs in the places people live, maybe that needs to be fixed first? Putting the jobs close to the people sounds like it would solve a lot of these transit issues by needing less of it.
I also think that getting jobs and places close to residential areas is a separate issue as we still need the bike lanes on the most unsafe areas. The two main things I think of are:
1. The folks working at major employers need bike access as well. Factories, call centers, distribution centers and large offices. Some of these places just aren't suited for neighborhoods, though they can be close by. It is much easier to get proper use of bike lanes if some or many of the big places have such access.
2. It actually takes more work to get the places closer, at least in the states. This is in no small part because of zoning and red tape. I don't really want to downplay that it'd take a slight difference in society as well - along with the likely need to subsidise som of the places.
