Keep in mind, there's a lot more that goes into the wildly superior Dutch infrastructure than just which streets get bike lanes along them. Roads are also fundamentally deferential to pedestrian and bike traffic there. As in, crossings are elevated above the road, which has a surprisingly effective impact on the culture and behaviors around modes.

The other issue with bike infrastructure in MA is also the reason we see pockets of it done so well-- cities here have way more power than in other states. It's a lot easier to get this stuff implemented here with purely local efforts than, say, in WI or wherever. We also just straight up generally love biking here. It's still totally baffling to me how that fucking gremlin thought he could run for mayor of Somerville on an explicitly antibiking platform. I also wish we could get our shit together in Medford on this, but my city is so god damned broke, I don't think we could afford the paint for slapping down lines.
