Musk retweeted a post by @nickshirleyy, which highlighted that the California High-Speed Rail project has cost $15 billion since 2008, yet has not connected any cities or laid any tracks. The project's total estimated cost is over $200 billion and is considered almost impossible to complete. The tweet also contrasted this with China's high-speed rail development during the same period, stating that China has built over 30,000 miles of high-speed rail network, while California still has zero. Additionally, over $500 million has gone to contractors unable to perform, and houses are being built along the planned route, causing farmers to lose their farms.
