Iterating a bit more

🟢 Easily walkable (≤15 min): 38 amenities (15%)
🟡 Just outside reach (15-30 min): 113 amenities (44%)
🔴 Too far to walk (>30 min): 64 amenities (25%)

113 amenities (from OSM) are tantalizingly close but just outside the 15-minute neighborhood

Walk Score gives this a 90/100. Their 15-minute walksheds look great!

But I mapped the ACTUAL amenities (from OSM which I know are great & accurate). 87% of meaningful amenities in the area are outside that 15-minute zone.

We're not measuring what matters.

Built this in 1 hour using OSM data + Python. The diamond shape shows how far you can actually walk in 5/10/15 minutes using real sidewalks & amenities. Explore: kepler.gl/demo/map?map...

I wish #flickr would do a better job with these cards. They don't do justice to any photo in portrait aspect. A shame because I think this is a good shot!

I went down a rabbit hole researching these vehicles recently because I remembered seeing one parked on Overtoom in #Amsterdam almost daily in the 1990s. I was always curious about them then but there was no WWW and #gopher / veronica didn’t offer up any information on them.

With their additional 3rd axle they had about a 4000lb load capacity. They had 3 tanks for a total of almost 300 liters of gasoline.
