Ever zipped over the speed limit, or glided past a stop sign when no one’s around?
When it comes to obeying traffic laws, “we’re all criminals,” says Wesley Marshall, an associate professor of civil engineering at the University of Colorado.
After surveying 18,000 people, Marshall is trying to understand why cyclists, in particular, might bend or flat-out ignore traffic regulations.
