In a survey of larger cities, Portland, OR had the highest percentage of bike commuters at 3.5 percent. Nationwide, the share of commuters biking to work in 2006 was 0.4%.
In the chart, "SOV" means Single Occupant Vehicle.
Motorcycles aren't SOVs? Nothing against motorcycles, I'm just trying to figure out why they were considered separately. Is driving a motorcycle significantly different from driving a small car? Is it difficult to find safe motorcycle parking? Et cetera?
