faqs[5]{q,a}:
  How far is San Jose to San Francisco?,About 48 miles downtown to downtown. Free-flow is about 50 minutes. Weekday peaks run 1 hour 20 to 1 hour 45. Pattern estimates, not live times.
  Is US 101 or I-280 better?,Most locals take I-280 unless they have a reason to be on 101. 280 is slightly longer, more pleasant, and frequently faster. Use 101 for SFO, Redwood Shores, or bay-side destinations.
  When is the worst time to drive?,Northbound toward SF 6:30–9:30 a.m. and southbound toward San Jose 3:30–7:00 p.m. Both ends are employment centres, so reverse commuting helps less than in most metros.
  Is Caltrain faster than driving?,About an hour on a local, less on an express — slower than a clear drive, comparable to or faster than a peak drive, with no variance. It wins downtown-to-downtown at peak and when you would pay SF parking.
  Does this page cover SFO or SJC?,SFO sits on 101 about two-thirds of the way north; SJC is at the southern end. Airport trips change the calculation — do not treat these downtown-to-downtown numbers as airport times.
