Even in California. If you compare the Transbay tube to the Bay Bridge, you really see how the Bay Area simply could not function as currently without BART. The tube services around 27,000 people at peak hour per direction, while the bridge only services just over 14,000 people (in 9,000 cars). Without the tube you’d need two additional 10 lane bridges to service peak demand. And that just wouldn’t be possible. https://youtu.be/HbZXtSnabWc?si=-mWIkQg3gTV-ZSMe&t=227 https://youtu.be/HbZXtSnabWc?si=-mWIkQg3gTV-ZSMe&t=227
