Only because the Bay area refuses to do highway improvements. There are STILL freeways that have not been rebuilt after the Loma Prieta earthquake of 1989. That was a perfect opportunity to go in an do major updates and reconstruction that would have helped the commuters AND laid the groundwork for an efficient public transport system.
But no, the asshats in charge and their environmental whacko string pullers had to go and screw that up. Once again demonstrating that they really don't care about the small guy, they care about power and that is all they care about.
If you truly wanted to get rid of gridlock the only way to do that is allow the vast majority of people who work in the paper pushing enterprises to telecommute. THAT would have a significant affect on all the commutes in the world, and contribute to employee well being and quality of life.
Um, which freeways have been neglected, and which have not been rebuilt?
I live here, and call bullshit. Your first paragraph is all opinion sans facts. I can post photos of on going and completed projects related to the quake of '89 and funding via the American Recovery and Reinvestment Act of 2009.
Traffic is a nightmare, but not for the reasons expressed. The big problem is every county has their own public transportation system and navigating form one to another can be a headache.
Planing is in the works to reestablish a ferry system, expand BART to the east in Contra Costa County and South to San Jose; Capitol Corrider Train already moves commuters from the East Bay Counties to Sacramento Co and beyond with convenient transfers to BART, and makes convenient transfers from BART to SFO and CAL train to Santa Clara County South, the ACE Train transports commuters from San Joaquin County to San Jose (Santa Clara County) with transfers local public transportation up through Santa Clara County to San Mateo County and connecting to BART at Millbrae.
I can walk one block from my home, get a bus to BART and from there get to anywhere in the world.
