I get its supposed to be a funny joke, but CA has some of the biggest transit projects in the country going on currently. CAHSR is wildly expensive, but its still being built, and will far and away be the best rail corridor in the country when its done.

LA has been building a decent amount of transit for how hard it is to get anything done there.

SF already has a fairly robust and solid transit network, and there have been some great maintenance projects done in the last 10 years to keep it going. Its only current major issue (imo) is the frequency, which still isnt the worst ever. MUNI is also getting new signaling to improve frequency, and a massive underground train station is going to get built at Salesforce (finally making use of a great transit hub).

BART is a great system with some much needed improvements happening currently, including new fare gates and all new signaling. They also just finished upgrading to the new fleet of cars, and came in under budget!

CalTrain is also rolling out their brand new electrified system in September, with hugely upgraded frequencies, that will make transit up/down the peninsula much better.

It isnt a ton when compared to other countries that build much more efficiently, but its still more than anywhere else in the country.
