What happens when you downzone?
Our new open-access research paper in @findingspress.org investigates effects of decades of downzoning in Chicago.
Findings:
—Downzoned areas added 1/7th of the new units as comparable non-downzoned areas;
—Downzoned areas became more white & were more expensive.

it's a happy coincidence that BEVs are apparently easier to automate at L4 (for city driving at least). ppl gave me different reasons why.
(i) w/ no transmission, control is smoother and thus easier for computer direction.
(ii) can link computers/sensors into already-elaborate electrical system.

One of my AV hot takes is that to avert the worst consequences of their mainstream adoption (such as hellish congestion and more induced sprawl) cities need to get serious fast about charging directly for road usage. And almost nowhere is.
Also because electrification will kill the gas tax.

In our model here, it’s optimal for small systems to have lower farebox recovery if they do charge. So if charging itself is costly, then small-enough systems should be free. but an exception would be crime problems. in IC hasn’t been the case

interesting how unintuitive falling aggregate demand is, and how relentlessly appealing the alternative explanations are. when I was young, nobody wanted to work due to video games. now AI Is taking the jobs. China, the extreme case, says it’s “involution.”

anyone know of an algorithm that makes offsets of overlapping routes like this automatically?
couldn't find anything that did exactly this, so a student is developing one for gtfs.
note in gtfs, the overlapping portions linestrings probably won't be identical.

Especially compared to when I was a kid. I am proud when I hear someone was impressed with Birmingham.

but i have a different take:
since i got my costco card, i drink much more milk.
now they think i am a cow, but with incredible powers (eg, pressure-washing, ebike).
you are NEVER "too old" to become someone new (eg a cow).
