That is utter bullshit. You could dedicate half the secondary roads to non motorized traffic and add a separates bicycle path alongside every highway and fluidity of the cars traffic wouldn't be affected at all. It would even improve.
We should re-evaluate what? The reality that the system we find ourselves in, means that families are distributed? Would you force people back together into the same region?
Some people (but by no means everyone) are better off away from their family and the town where they grew up.
Imagine that you are the fourth generation to move far away from your patents, as I am. There is not some community in which I have generational roots…and it was the prospect of conscription by the Tsar’s army that started it all. Not capitalism.
For me, employment someplace far away was the way out of where we weren’t from and that wasn’t for us.
Some people have a reason to stay. Those reasons are sometimes the reasons for other people to leave.
I hear what you are saying - if you love bikes long journeys are wonderful. I imagine motorcyclists or long distance runners could get the same buzz.
> It may not be for everyone but I want to live in a world where that experience feels accessible to as many as possible.
But let's not kid ourselves that this is a viable option for most people. And if you mean that we should get rid of even more roads for bike lanes, you are actually going to restrict people engaging with distant relations and friends.
