Ok most of what you're saying makes sense, but having gone to bike lanes in lower manhattan it seems like it's a lot of food delivery people 24/7 with the normal new yorkers you'd see on the subway during commuting hours. From a humanistic perspective it seems like it's a good thing to ensure that delivery drivers aren't killed by motor vehicles and have the ability to not conflict with sidewalk pedestrians? As a driver I would prefer they're not in my lane.

I suppose we'll agree to disagree on this one, there's like a bajillion books that assert the opposite so I will let those and the intertubes do the talking.

As it relates to the study, I'm a little confused how it relates to the above discussion. Is this a good or bad thing to have density of jobs relate to skill level? Wouldn't the historic development of these cities with thousands of years of human civilization in Europe vs. relatively recently developed US cities be a confounding factor in exploring land use patterns?

Yes, I should have mentioned that I specifically meant people using bike lanes for commutes. Bike lanes for work or for recreation are a totally different story, and I have nothing against them.

However, in this case it still reinforces my point: delivery by bike is a luxury good. It still is something that makes living in an utterly unaffordable area more bearable for people who have money.

I'm actually not saying anything that is not an accepted fact in urbanism.

No, it's not good. This means that good jobs force people to move closer to the centers of their concentration. This automatically reduces opportunities for other people.
