I imagine most Americans violate speeding and other vehicles moving laws far more often than jaywalking. I imagine the majority of Americans haven't actually crossed a street as a pedestrian in the last week.
Why would they? They drive from their home to their job to the parking lot of the grocery store to the drive through pickup line at school for their kids.
I'm one of the more transit/pedestrian/bike people in the group I routinely hang out with and I haven't actually crossed the street as a pedestrian in a few days.
