And car seat design might be quite a bit different—and perhaps simpler—in an urban environment where all vehicles are automated and never exceed 20 or 25 mph on most surface streets

Early preview of 2046 discourse! Looking forward to it

I’m guessing that at some point in our lifetimes, a dense U.S. city will seriously consider banning human-driven cars, and it will be interesting to see which political factions end up on each side of the issue

When the rap was released, there wasn’t even a 17-story apartment building on that site. It was a parking lot for old WMATA buses

I like that there’s an Alexandra Petri who is a humor columnist at The Atlantic (formerly of The Washington Post) as well as an Alexandra Petri who is a reporter at The New York Times covering plane crashes and natural disasters

I’m looking forward to this. Hopefully it fares better than the 3 tenants in that location since 2015 (Taylor Gourmet, Lebanese Taverna, and Starbucks)

Reminds me of how one of the top car YouTubers also happens to be the individual who possesses the YIMBY license plate in the state of California. Two worlds colliding. (I like both Odd Lots and Alison Roman, obviously.)

I still find it amusing that CVS originated as Melville Shoe Company, which opened for business as a shoe store in New York in 1892. Sheinhardt Wig Company moment

I ate a small container of blackberries earlier this evening. They weren’t great—that’s okay, I’ll still keep eating that garbage

15 years ago, if you told me this idea—at least as a mainstream perspective in American politics—had been relegated to the ash heap of history, I‘m pretty sure I would have believed you. (Oops.)

I’m not sure this is correct?

Based on the image of Tim Miller in the top right as well as the “I was on with Jon Stewart” line in the preceding paragraph, I’d guess the highlighted excerpt was said by Tim Miller (not Will)

Thank you for posting the photo. Every time the Celsius versus Fahrenheit debate pops up on social media in the future, I will think of this exchange.

I’m not sure about the news, but digital thermostats in Celsius countries almost always offer 0.5° increments in my experience

If every country in the world switched to Kelvin, after enough time, people would get used to that scale—especially those who grew up with it—and those advocating a return to Celsius or Fahrenheit would probably be mocked for suggesting that C or F is more intuitive

I like that these ranges are dramatically different

It’s funny to me that certain portions of the McValue menu are compatible with some, but not all, app exclusive coupons (which may be used only once every 15 minutes). If you really want the best deal, you have to do some (pretty basic) math. Our favorite retired bond trader probably hates this

“How much residential floor area would NYC gain if every building under six stories in a census tract within 400m of a subway station were heightened to six stories while retaining its existing footprint” took me about 30 minutes (with no GIS skills)

Looks like TfL has about 2.25x as many passenger journeys as NYCTA + MTA Bus Company has unlinked passenger trips (2024 data)

I still think about how TfL buses transport 47% the number of passenger journeys of all U.S. public transit bus/BRT/commuter bus/trolleybus lines combined
