As a log-time Sunnyvale resident and ardent booster, all I can say is OUCH! - I prefer to call commute route coverage "spotty" - it is a big city. Plus, there is an active BPAC, and a friendly city council, so they are working to improve matters. Check out the newest Sunnyvale Bike map at http://sunnyvale.ca.gov/NR/rdonlyres...nalmapside.pdfhttp://sunnyvale.ca.gov/NR/rdonlyres...nalmapside.pdf
and you can find good routes through some areas.
