I will still be using the cross walks everywhere I go. Because there's no shortcut across the street that is worth me stopping traffic or getting hit by a car. Jaywalking is for selfish and impatient people who are bad at assessing risk. Unless the street is completely empty, I guess.
As someone who has never lived in a city this is strange to me. I live in a relatively dense part of Louisiana, but around here you couldn't walk at all without jaywalking. There aren't even sidewalks in a lot of places. You just walk along the side of the road.
What I think is crazy is all of the cities that just don't build sidewalks. I understand in certain rural areas, but yeah, many midwestern and southern cities are downright hostile to pedestrians.
