I don't know what "statistically normal" means, but I'd estimate that 20-50% of my colleagues are in the same position as me and so would benefit from better cycle infrastructure.
The average commute in miles for Americans is 16 miles and 26 minutes for one way. That's 32 miles and 52 minutes for a round trip every day.
Let's assume we decide we want to get the "Average" American biking to work instead. We have to figure out how we can convince people who spend an hour on the road everyday to spend 8 hours on the road biking instead, or give up their houses and pay more for smaller accommodations closer to their work to shorten the distance.
The average speed of a bike commuter is under 10 mph. 32 miles thus takes more than 3.2 hours, * 2 = 6.4 hours per day biking the same distance as the average American commuter currently drives in 1/3 the time. Toss in a couple hills and you could easily hit 8 hours total biking time.
