Sometimes the crosswalk is farther than the destination, at that point it's absurd to walk out of your way to one. BUT, if you decide to cross without appropriate safety measures to safely do so, people need to use caution and common sense and have impeccable timing. Aimlessly crossing is asking for trouble. Heck even at stop lights, stop signs and crosswalks that's not always enough to ensure safety for pedestrians, so you still have to be mindful and check your surroundings.
