Facts

Tokyo has a high population density. 
More than Carrick-on-Shannon for example. But people are very obedient when it comes to crossing the road. There is no jaywalking. 
If Carrick-on-Shannon had the same population density as Tokyo, 687 pedestrians would die from jaywalking. Per second. 
Except between the hours of 04.00am and 06.00am when the death toll would fall to a slightly less scary 643 instances per second.
