This makes me want to jump up and shout "YES YES YES!"
When I worked at Google, I rode a bike about 3 miles to work most days, because ~80% of the trip was on Steven's Creek Trail. When I moved to my new house about 1.5 miles away, I stopped riding because the only route was the Crossover of Death at Rengstorff & Charleston. (If you've driven through there, you know what I mean; and now imagine riding that on a bicycle. Turns out daily morning dread terror is even more effective than morning coffee!)
Eventually they opened the Permanente Creek Trail and I rode that quite a bit, but still not nearly as much as the longer trip -- because I still had to ride some unfriendly streets, and notably cross Rengstorff at an intersection with no light.
Similarly, I could ride to my current workplace in Palo Alto about 4 miles away, but I haven't tried it yet because I'd have to cross El Camino, which is super intimidating.
This entire study just 100% spot-on nails it: fix the intersections, give me just a few more shrewdly-placed safe and friendly routes, and I'd ride most every day. http://bikesiliconvalley.org/betterbiking/google-bike-vision-plan-2015/
