I guess I'm very fortunate where I live. The 3 in my area are nearly contiguous (and there are active plans to connect the remaining 2 gaps and pave the very end of the main one), well-planned, pleasant, reasonably safe, and actually can get you places faster than taking surface streets. Kind of like some freeways. I realize that's often not the case. I'm most grateful that the planners in my area went with quality over quantity.
