I'm calling BS on Silicon Valley having a well-developed transit system.
I live in San Jose and work in Palo Alto. Most mornings it takes me exactly one hour from my front door to take a local bus down the street, pick up the express bus to Palo Alto, and another local bus to the front door of my workplace. The afternoon commute is one to two hours long, depending on 280 traffic. Or four hours if a gravel truck spills across all lanes like it did a few months ago.
VTA transit routes (e.g., the transit agency responsible for mess that is silicon valley) have decided that the only viable transit corridors/routes are south san jose to downtown san jose and mountain view to cisco (aka north-sanjose).
That's correct. Homes in the South and jobs in the North determined the transit lines back in the 1980's. VTA was supposed to have a half-dozen East-West light rail lines but those were never built. When San Carlos got shutdown as a street through San Jose State University in the 1990's, the county built the foundations and covered it up with 18 inches of top soil for a future light rail line. The only major East-West line being built is the BART extension from Fremont.
Santa Clara (in the heart of Silicon valley)
Santa Clara (Intel) haven't been the heart of Silicon Valley in decades. It's Menlo Park (Facebook).
[...] (unless those points are walking distance to light-rail or caltrain).
That's why mixed-developments with stores on bottom and four story of apartments on top are sprouting up along the transit lines. If you don't live near a major transit line and don't work near a major transit line, blaming public transit isn't going to fix it. I live near several major transit lines, so I'm an hour away from work in North San Jose, Mountain View or Palo Alto.
