If you want to donate to Democratic candidates without getting spammed with endless fundraising emails, I recommend Oath. I used it in 2024 & again this year. It worked well, helping me identify tossup races for Arizona State candidates (who I supported to help keep election deniers out of office).

Today in NYC, @parkingreform.org is arguing that charging for curb parking, converting parking spaces into bike lanes, removing minimum parking mandates, and building apartments on parking lots is a good way to reduce pollution. This will upset some environmentalists. Oh, well!

Heat pumps reduce pollution, regionwide. So do solar panels, EV chargers & other green tech. For these technologies, states shouldn't let cities impose onerous & expensive rules that vary by city. If otherwise law-abiding citizens routinely break the rules, that's a good sign they are too onerous.

US model fire codes demand wide roadways (with 20 or more feet of clear width), even on very low-traffic residential streets. Am I right in thinking that few if any other nations demand such wide streets?
A birds eye view photograph of a single-family house subdivision in Carson City Nevada. In the left foreground can be seen a wide, slightly meandering street. The street is approximately 36 feet wide from curb to curb, including enough room for two 8-foot parking lanes and 20 feet of width in between them. While the parking lanes exist, no cars are parked in them. The street has narrow sidewalks on both sides, but no street trees. The resulting street look like a Speedway. Motorists can easily and comfortably navigate it at speeds far in excess of the 25 mile-per-hour posted speed limit, and it is likely that many of them do just that. Photo by Dan Burden.

In California, new state laws require many cities to allow apartments near transit, so why aren't more apartments being built? In part, because so many cities break the law.

Pew Charitable Trusts found that since 2017, housing in Austin has become MORE affordable for the average worker, thanks to the construction of more than 120,000 new homes.
A bar chart titled, "Figure 2 With More Housing Supply, Austin’s Median Rent Became Affordable to Those Earning Lower Incomes Share of Austin’s median income needed to afford Austin’s median rent, 2017 and 2024." The chart shows that in 2017, the share of Austin's median income needed to afford Austin's median rent was 95%. By 2024, that figure had fallen to 84%.

The chart footnote reads:
"Notes: The above figures assume affordability based on a household spending 30% of its income on rent. Rental unit affordability is calculated as follows: Numerator is monthly rent for a one-bedroom unit (from Apartment List) x 12 months / 0.3 (the 30% of income going toward rent); denominator is Austin city area median income for a one-person household.

Sources: Rent data from Apartment List downloaded Dec. 23, 2025; AMI for a one-person household from U.S. Census Bureau’s American Community Survey 2024 one-year estimates"
