IMO cities shouldn’t just adopt more cycle lanes, but also shut down major roads close to their centre and in areas with lots of non-commuter traffic to make cycling safer. At least in the US, many cities were planned specifically to incline residents to buy cars to get around. Important facilities are placed in weird places or far apart to make it impossible to reach them with any semblance of convenience without a motor vehicle. So it’s a little difficult to ask already well established American cities to accommodate cycling, it requires replanning the city, and local governments aren’t willing to pay potentially millions to make that happen.

I live in Texas, every attempt Texan cities have made to become accommodating to cyclists has failed horridly, and most of it just has to do with how cities have been designed. You can’t expect cyclists and motorists to share dangerous roads and be harmonious, especially when local government’s aren’t willing to build cycling bridges over interstates, so cyclists end up barreling into oncoming traffic. So, even sectioning off parts of the city to be motorless transport only zones kinda fails to make it safer or worth doing.

This is a very long (and half asleep) rambly way of saying; it’d be cool to have in the US, but it’s not strictly possible.
