I really doubt it is. The biggest barrier must be the weather - biking in the cold and rain is just super unpleasant for an average person, especially for errands and commute. I know you can prep, but it's still pain. I gave up due to Seattle rain, and I am not even an average commuter - I'd go on a major hike on a rainy day... but biking in the same weather just sucks so much. And Seattle is mild.
I can see how it can be the 2nd biggest barrier, although for me in Seattle it's the fear of my bike being stolen. Dunno if I'm lucky or what, but the only 2 times I've been in serious cycling accidents it was 100% my fault (both times at 20+ mph passing cars on the left - rear ended another car once, and rode into tram tracks the other). I'm still afraid of cars but not as much as having to uber back in wet cycling clothes if my bike gets stolen :)
