I'd argue the biggest impediment to good cycling infrastructure is the low utilization of the existing cycling infrastructure. I had a friend who insisted that most people want to cycle to work, but they are lacking the infrastructure. If we only build more bike lanes and bike paths, more people would choose to cycle instead of drive. The thing is, my city has an extensive set of bike paths. They're really nice and are a viable way to get places. They're also rarely used except for exercise or leisurely strolls. Given most bike paths in my city are empty most of the time, why would we spend money on more cycling infrastructure? The low utilization - not a social perception - are why spending more money would be a waste.
