US government's policy toward the Big 3 automakers—encouraging them to invest in massive, US-only SUVs & trucks, now encouraging them to underinvest in EVs—has reinforced their global irrelevance.
Ford sold 33% fewer vehicles worldwide in 2024 than 2015! GM sold 40% fewer vehicles!

The metro here, like in Paris, uses rubber tires on the cars. Helps reduce tunnel noise.

I live just a few blocks from here. Sad to see CCA close, and curious (and excited) about Vanderbilt's new campus in SF.

Booming S.F. neighborhood will be home to new college campus — a blow for downtown
Though San Francisco’s mayor urged major academic institutions to open a campus in the city’s faltering downtown, Vanderbilt University chose instead a fast-growing pocket of the city.

One benefit of creating unique icons for each metro station (matching its name) is that it can help illiterate riders (or non-native speakers) navigate the system.

When the conservative-leaning 'it's time to build!' crowd support this administration, it's because they....don't actually want to build.

Very interesting to see Mexico City employ the "women + children" only first car on its metro system. Polling in the US has shown that this would likely be popular among female riders.
